The 1JM adapter is a straight cross standard adapter that joins a JIC 74\u00b0 cone male end, made to SAE J514 with an inch thread, to a metric male 60\u00b0 seat end with a metric thread in the ISO 8434-6 family. It is the hydraulic conversion adapter used when a machine built around SAE inch tube connections has to meet a manifold, cylinder or valve block machined with metric ports.<\/p>\r\n\r\n\r\n\r\n
Both connection ends must match their mating port exactly in thread form, seat angle and seat condition, because that match is the precondition for eliminating leakage at the conversion point. A 1JM adapter does not convert one sealed joint into another kind of joint: it carries two different sealing systems on one body, an SAE inch cone on one side and an ISO metric seat on the other.<\/p>\r\n\r\n\r\n\r\n
Sealing principle of this series: connection 1 is a 74\u00b0 external cone that seats metal-to-metal on the mating 74\u00b0 internal cone, and connection 2 is a 60\u00b0 external cone that seats metal-to-metal on the mating 60\u00b0 internal seat. No elastomer sits in either sealing path, and the thread is not the sealing element on either end.<\/p>\r\n\r\n\r\n\r\n
Ventajas principales<\/h2>\r\n\r\n\r\n\r\n
\r\n
One body carries an SAE J514 inch thread and an ISO 8434-6 metric thread, so an inch line meets a metric port without an extra reducer.<\/li>\r\n\r\n\r\n\r\n
Two cone angles on one part, 74\u00b0 on the E end and 60\u00b0 on the F end, each matched to its own port standard.<\/li>\r\n\r\n\r\n\r\n
Reducing combinations across the range, from M10x1 up to M26x1.5 on the metric side and 7\/16″x20 up to 1.1\/16″x12 on the JIC side.<\/li>\r\n\r\n\r\n\r\n
Metal-to-metal cone seals at both ends, with no elastomer in the joint to age, swell or extrude.<\/li>\r\n\r\n\r\n\r\n
Centre hex from 14 mm to 32 mm across flats, so standard wrenches fit without special tooling.<\/li>\r\n\r\n\r\n\r\n

1. What a 1JM Adapter Does<\/h2>\r\n\r\n\r\n\r\n
A 1JM adapter is a straight stud with a JIC 74\u00b0 cone male end on one side and a metric male 60\u00b0 seat end on the other. It connects a tube assembly terminated with a JIC 74\u00b0 cone nut and sleeve to a port machined with a metric 60\u00b0 internal seat.<\/p>\r\n\r\n\r\n\r\n
This JIC adapter does one job: it moves fluid between an SAE inch port and an ISO metric port without changing direction. The E column of the size table is always the JIC 74\u00b0 cone end, printed in the SAE style such as 7\/16\"X20<\/code>. The F column is always the metric 60\u00b0 seat end, printed as a metric thread such as M14X1.5<\/code>. A row such as 1JM-06-14 therefore carries a 9\/16″x18 JIC cone at one end and an M14x1.5 metric cone seat at the other.<\/p>\r\n\r\n\r\n\r\n
This is a cross standard hydraulic conversion adapter in the strict sense. The two ends of this male adapter belong to different standards, thread forms and seat angles, so a 74\u00b0 cone will not seat in a 60\u00b0 seat and a 60\u00b0 stud will not seat in a 74\u00b0 cone. The conversion has to be made by a body that carries each seat at its own end.<\/p>\r\n\r\n\r\n\r\n
Because both seals are cone seals, the condition of the two cones governs the result. A nicked or flattened cone leaks no matter how much torque is applied afterwards, and section 4 covers the handling rules that keep both cones serviceable.<\/p>\r\n\r\n\r\n\r\n
2. 1JM Specifications<\/h2>\r\n\r\n\r\n\r\n
2.1 Connection 1 – JIC 74\u00b0 cone male end (E)<\/h3>\r\n\r\n\r\n\r\n

Read the E column as the JIC adapter end in the SAE J514 inch thread standard and the F column as the ISO metric end. The two blocks above are deliberately mirrored so a buyer can map one end to one port on the machine and the other end to the second port without translation.<\/p>\r\n\r\n\r\n\r\n
2.3 Construction and Materials<\/h3>\r\n\r\n\r\n\r\n
The body is machined from bar stock on CNC lathes. The two threads, the 74\u00b0 cone, the 60\u00b0 cone and the hex are turned in one setup so the two ends stay concentric and the seat angles are held relative to one another.<\/p>\r\n\r\n\r\n\r\n
\r\n
Body material: carbon steel as standard; 304 stainless steel or 316 stainless steel on request; brass for selected sizes.<\/li>\r\n\r\n\r\n\r\n
Plating and finish: trivalent chromium zinc plating (Cr3+) for carbon steel as standard; zinc-nickel plating available. Plating thickness and corrosion performance are confirmed per order rather than published as a series figure.<\/li>\r\n\r\n\r\n\r\n
Seal material options: both joints in this series are metal-to-metal, so the stud itself carries no elastomer. Where the same circuit uses elastomer-sealed components, NBR, FKM and EPDM are the available seal compounds.<\/li>\r\n\r\n\r\n\r\n
Machining process: bar-stock turning, each thread form produced to its own port standard, both cones checked against the drawing.<\/li>\r\n\r\n\r\n\r\n
Hex feature: a single centre hex (S1) on the body, from 14 mm to 32 mm across flats depending on size. There is no bulkhead feature in this series.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
2.4 Pressure and Temperature<\/h3>\r\n\r\n\r\n\r\n
Working pressure for a 1JM adapter is not set by the series code. It is governed by the thread size, the wall thickness of the stud and the tube, the sealing method and the material selected. Working pressure for these sizes is confirmed per order by HENGHUA engineering, based on the thread size, sealing method and material selected.<\/p>\r\n\r\n\r\n\r\n
Temperature is a material question and is stated here as a material fact rather than a performance claim. For NBR seals, the working range is approximately -30\u00b0C to +100\u00b0C. For FKM (Viton-type) seals, it is approximately -20\u00b0C to +200\u00b0C. For EPDM seals, it is approximately -40\u00b0C to +120\u00b0C. These figures apply to the elastomer rather than to the metal cone joints of this series.<\/p>\r\n\r\n\r\n\r\n
Carbon steel with zinc plating suits general hydraulic service; specify 304 or 316 stainless steel for corrosive, offshore or washdown environments, where the metric end of a machine is often the side exposed to the more aggressive conditions.<\/p>\r\n\r\n\r\n\r\n
2.5 Part Number and Dimension Table<\/h3>\r\n\r\n\r\n\r\n
The table below is the complete printed size range of the 1JM series. All length and hex dimensions are in millimetres.<\/p>\r\n\r\n\r\n\r\n
What each column means<\/strong><\/p>\r\n\r\n\r\n\r\n
\r\n
N.\u00ba DE PIEZA.<\/strong> – the HENGHUA part number. The series prefix 1JM<\/code> is followed by the size code of the JIC end and then the size code of the metric end, separated by a dash.<\/li>\r\n\r\n\r\n\r\n
E<\/strong> – the thread of connection 1, the JIC 74\u00b0 cone end, printed as diameter x threads per inch in the SAE style, for example 1\/2\"X20<\/code>.<\/li>\r\n\r\n\r\n\r\n
F<\/strong> – the thread of connection 2, the metric 60\u00b0 seat end, printed as a metric thread, for example M14X1.5<\/code>.<\/li>\r\n\r\n\r\n\r\n
A<\/strong> – the length from the end of connection 1 (the JIC cone end) to the hex face on that side, in millimetres, as marked on the series drawing.<\/li>\r\n\r\n\r\n\r\n
B<\/strong> – the same measurement at connection 2 (the metric seat end), in millimetres.<\/li>\r\n\r\n\r\n\r\n
L<\/strong> – the overall length of the part from end to end, in millimetres.<\/li>\r\n\r\n\r\n\r\n
S1<\/strong> – the hex across flats, in millimetres, used to hold the body with a wrench during assembly.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
Thread size and dash chart<\/strong><\/p>\r\n\r\n\r\n\r\n
The JIC size code follows the SAE convention based on the nominal tube outside diameter in sixteenths of an inch. The metric thread is printed directly.<\/p>\r\n\r\n\r\n\r\n
\r\n
\r\n\r\n
\r\n
JIC size code<\/th>\r\n
JIC thread printed in this series<\/th>\r\n
Metric threads available at the F end<\/th>\r\n<\/tr>\r\n<\/thead>\r\n
Nut and sleeve are ordered separately.<\/strong> The 1JM stud does not include them, and the two ends need different nuts because the threads belong to two standards. Use nut NB200 with sleeve NB500 for metric tube, and nut NB200 with sleeve NB300 for inch tube.<\/p>\r\n\r\n\r\n\r\n
3. How to Read a 1JM Part Number<\/h2>\r\n\r\n\r\n\r\n
A 1JM part number has three elements: the series prefix and the two size codes, one for each end. There is no sealing suffix on this series.<\/p>\r\n\r\n\r\n\r\n
The prefix 1JM<\/code> identifies the geometry and the thread pair: a straight stud with a JIC 74\u00b0 cone male end and a metric male 60\u00b0 seat end. Other prefixes in the same catalogue identify a metric male captive seal end, an NPT male end or a BSP male end.<\/p>\r\n\r\n\r\n\r\n
The first size code is the JIC end, taken from the SAE dash convention, and the second size code is the metric end, taken from the metric thread designation. The two codes follow different numbering systems, which is the most common source of ordering error on a cross standard adapter.<\/p>\r\n\r\n\r\n\r\n
Worked example: 1JM-06-16.<\/strong><\/p>\r\n\r\n\r\n\r\n
\r\n
1JM<\/code> – straight stud, JIC 74\u00b0 cone male to metric male 60\u00b0 seat.<\/li>\r\n\r\n\r\n\r\n
06<\/code> – connection 1 is the SAE J514 size with a 9\/16″x18 thread.<\/li>\r\n\r\n\r\n\r\n
16<\/code> – connection 2 is the metric seat end with an M16x1.5 thread.<\/li>\r\n\r\n\r\n\r\n
From the table: A is 14.1 mm, B is 12 mm, L is 35 mm and S1 is 22 mm.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
A buyer ordering 1JM-06-16 therefore receives a male adapter whose JIC end takes a 9\/16″x18 tube assembly and whose metric end screws into an M16x1.5 port with a 60\u00b0 internal seat. Check that the metric port is a 60\u00b0 seat port rather than a gasket-sealed port, because the sealing system changes with the port, not with the thread.<\/p>\r\n\r\n\r\n\r\n
4. Installation and Fitment<\/h2>\r\n\r\n\r\n\r\n
Both ends of a 1JM adapter are cone joints, so both ends are assembled by hand first and then tightened to seat the cone. HENGHUA does not print a single torque figure for the series, because the correct tightening depends on the mating nut and seat, the tube material and the wall thickness. Confirm the tightening figure with HENGHUA engineering per order. Tighten in stages, and never use a pipe extension or an impact tool on a cone joint.<\/p>\r\n\r\n\r\n\r\n
Cone seat handling: keep the stud cones and both mating seats clean and free of nicks. Wipe each cone with a lint-free cloth and inspect it under good light before assembly. An overtightened cone is already deformed and must be replaced.<\/p>\r\n\r\n\r\n\r\n
Thread preparation: on this series neither thread is the sealing element, so do not wrap the threads with thread tape or use sealant as a leak cure. A light oil on the threads lets the nuts run up smoothly without galling.<\/p>\r\n\r\n\r\n\r\n
Contamination control: cap open ends before storage and before the line returns to service, because debris that reaches either seat scores the faces and produces a seep that no further tightening removes.<\/p>\r\n\r\n\r\n\r\n
Alignment: bring each tube squarely to its stud end before starting the nut, because a tube pulled sideways into a cone loads the seat on one side and weeps at first pressure. On a cross standard joint, check the alignment twice, because tightening one end can pull the other end off centre.<\/p>\r\n\r\n\r\n\r\n
Reuse policy: the stud body with undamaged cones can be reused. The nuts and sleeves are the wear items, and the assembly is replaced whenever a cone shows galling or a bright polished band.<\/p>\r\n\r\n\r\n\r\n
Common fitment errors and their symptoms:<\/p>\r\n\r\n\r\n\r\n
\r\n
Forcing a 74\u00b0 cone against a 60\u00b0 seat, or the reverse. Symptom: the nut runs up but the joint weeps at first pressure, and the two cones are visibly mismatched under inspection.<\/li>\r\n\r\n\r\n\r\n
Threading a 60\u00b0 seat part into a gasket-sealed metric port. Symptom: the part bottoms on the flat face instead of seating, and no cone contact is made.<\/li>\r\n\r\n\r\n\r\n
Overtightening to stop a seep. Symptom: a deformed cone and a leak that returns immediately.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
Confirm the part number against the line list, and check that the E end is the JIC 74\u00b0 cone and the F end is the metric 60\u00b0 seat that the two mating ports require.<\/li>\r\n\r\n\r\n\r\n
Inspect both cones and both mating seats for nicks, corrosion and previous overtightening marks.<\/li>\r\n\r\n\r\n\r\n
Clean the cones and the threads with a lint-free cloth and a compatible cleaning fluid.<\/li>\r\n\r\n\r\n\r\n
Fit the nut and sleeve to each tube, then bring each tube square to its stud end by hand.<\/li>\r\n\r\n\r\n\r\n
Run each nut up by hand until it is snug, then tighten in stages to the recommended figure without an extension bar.<\/li>\r\n\r\n\r\n\r\n
Pressurise the circuit, check both ends for weeping, and re-check the tightness after the first thermal cycle.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n
5. Applications and Industries<\/h2>\r\n\r\n\r\n\r\n
Application tags for this series: hydraulic systems, water jetting, oil and gas, industrial equipment, construction machinery, agriculture, marine, material handling. This kind of hydraulic adapter is specified by its thread pair rather than by industry, so the same part serves several sectors.<\/p>\r\n\r\n\r\n\r\n
Cross-standard equipment integration.<\/strong> Imported machinery frequently arrives with a metric manifold and SAE inch tube lines, or the reverse. This series provides the interface the two sides need, and rows such as 1JM-06-16 let one part step between a smaller JIC line and a larger metric port without a second reducer.<\/p>\r\n\r\n\r\n\r\n
Repair and replacement.<\/strong> Maintenance crews fit this series when a damaged tube end or a seized metric stud has to be replaced with an inch line on site. Because the printed table spans many metric threads against each JIC size, the replacement is usually drawn from stock.<\/p>\r\n\r\n\r\n\r\n
High-pressure test benches.<\/strong> Test rigs need repeatable, replaceable interfaces between the pump side, the gauge line and the test article. The metal-to-metal cone joints of this hydraulic adapter give a stable seal across thermal cycles, and the centre hex holds the stud while each nut is tightened.<\/p>\r\n\r\n\r\n\r\n
6. Replacement and Cross-Reference Guide<\/h2>\r\n\r\n\r\n\r\n
Cross-reference for this series is organised by standard and sealing method, never by brand. Two fittings interchange only if the standard, the thread size, the seat angle and the seal type all match.<\/p>\r\n\r\n\r\n\r\n
A 1JM adapter is a JIC adapter with an SAE J514 74\u00b0 cone stud at one end and an ISO 8434-6 metric 60\u00b0 seat stud at the other. It is not interchangeable with a JIC 37\u00b0 flare fitting, which seals on a 37\u00b0 conical flare face, and it is not interchangeable with an ORFS fitting, which seals a flat face against an elastomeric O-ring under SAE J1453. It is also not the same part as a metric stud with a captive or bonded seal: the 60\u00b0 seat version in this series seals on a machined metric cone, while the captive seal version seals on a flat face through an elastomer washer and leaves the thread outside the sealing path.<\/p>\r\n\r\n\r\n\r\n
To identify the correct replacement, measure three things.<\/p>\r\n\r\n\r\n\r\n
\r\n
Thread on both ends.<\/strong> Measure the outside diameter and the pitch of each thread and record them separately. A 9\/16″ end measures about 14.3 mm outside diameter with 18 threads per inch, while an M14x1.5 end measures about 14 mm with a 1.5 mm pitch. The two look close in diameter and do not interchange.<\/li>\r\n\r\n\r\n\r\n
Seat angle.<\/strong> Use a seat angle gauge or a straight edge against each cone. A 74\u00b0 cone is a wide, shallow cone and a 60\u00b0 seat cone is steeper. If the angles differ, the parts do not interchange regardless of any thread match.<\/li>\r\n\r\n\r\n\r\n
Seal type.<\/strong> Confirm whether each joint relies on a metal cone or on an elastomer. Both ends of this series are metal cone joints; a captive elastomer washer at the metric end belongs to a different series.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n
Where one of the ports is a pipe thread, a cross standard hydraulic conversion adapter is the correct part rather than a forced thread. Record the three measurements with the part number and HENGHUA can match the replacement from the printed table.<\/p>\r\n\r\n\r\n\r\n
7. Ordering, Packaging and Delivery<\/h2>\r\n\r\n\r\n\r\n
To order, give the following information:<\/p>\r\n\r\n\r\n\r\n
\r\n
Series code: 1JM<\/code>.<\/li>\r\n\r\n\r\n\r\n
Full part number, for example 1JM-08-20, taken from table 2.5.<\/li>\r\n\r\n\r\n\r\n
Thread sizes for the JIC end and the metric end, read from the E and F columns.<\/li>\r\n\r\n\r\n\r\n
Nut and sleeve requirement for each tube, including the tube standard (metric tube uses nut NB200 with sleeve NB500; inch tube uses nut NB200 with sleeve NB300), because these are ordered separately from the stud.<\/li>\r\n\r\n\r\n\r\n
Seal material for the elastomer-sealed components in the circuit (NBR, FKM or EPDM), plus body material and plating: carbon steel with trivalent chromium zinc plating, zinc-nickel plating, or 304 or 316 stainless steel.<\/li>\r\n\r\n\r\n\r\n
Quantity, and the destination and packing format required.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
Packaging formats: bulk cartons for line-side consumption, small boxes for distributor shelves and labelled bags for service kits, each labelled with the part number, the thread at each end and the quantity.<\/p>\r\n\r\n\r\n\r\n
Sample orders: validation samples and first-article parts are available for OEM programmes, including drawing-based manufacture of specials where the printed table does not cover the required thread combination.<\/p>\r\n\r\n\r\n\r\n
Lead time is confirmed per order, because it depends on the size, the material, the plating and the quantity. As a hydraulic adapter manufacturer and hydraulic adapter supplier, HENGHUA can quote the stud, the nut and the sleeve as one matched kit.<\/p>\r\n\r\n\r\n\r\n
8. FAQ<\/h2>\r\n\r\n\r\n\r\n
What is the difference between JIC 37\u00b0 flare and ORFS, and which should I use?<\/strong><\/p>\r\n\r\n\r\n\r\n
A JIC 37\u00b0 flare joint seals metal-to-metal on a 37\u00b0 conical flare face under SAE J514. An ORFS joint seals a flat face against an elastomeric O-ring under SAE J1453. Choose the family that matches the port already on the equipment, because the two are not interchangeable. The 1JM series is on the JIC 74\u00b0 cone side of SAE J514, and its other end is a metric 60\u00b0 seat, so confirm both seat angles before ordering.<\/p>\r\n\r\n\r\n\r\n
Can NPT and BSPT be interchanged?<\/strong><\/p>\r\n\r\n\r\n\r\n
No. NPT is a 60\u00b0 taper pipe thread under ANSI\/ASME B1.20.1, and BSPT is a 55\u00b0 taper pipe thread under ISO 7-1. The thread form, the angle and the pitch differ, so the two will not seal even though some sizes start by hand. Neither end of this series is a pipe thread, so a pipe port on the machine always needs a dedicated cross standard adapter rather than a forced thread.<\/p>\r\n\r\n\r\n\r\n
How do I identify the correct 1JM size?<\/strong><\/p>\r\n\r\n\r\n\r\n
Measure the thread outside diameter and the pitch at each port, then read across the E and F columns of table 2.5 for that thread pair. When the JIC thread, the metric thread and both seat angles match a printed row, that row is the correct part number. Read the two columns separately, because the JIC size code and the metric thread are two different numbering systems.<\/p>\r\n\r\n\r\n\r\n
What seal material should I select for my fluid and temperature?<\/strong><\/p>\r\n\r\n\r\n\r\n
For general mineral hydraulic oil within -30\u00b0C to +100\u00b0C, NBR is the usual choice. For higher temperatures up to approximately +200\u00b0C, or where the fluid attacks NBR, choose FKM (Viton-type). For water, water-glycol and many water-based fluids, EPDM is the option, with a working range of approximately -40\u00b0C to +120\u00b0C. Both joints in this series are metal-to-metal, so the seal material applies to the elastomer-sealed parts of the same circuit.<\/p>\r\n\r\n\r\n\r\n
How is the working pressure of this adapter determined?<\/strong><\/p>\r\n\r\n\r\n\r\n
Working pressure is not fixed by the series code. It is governed by the thread size, the wall thickness of the stud and the tube, the sealing method and the material selected. Working pressure for these sizes is confirmed per order by HENGHUA engineering against the intended circuit.<\/p>\r\n\r\n\r\n\r\n
What is the minimum order quantity and can I get samples?<\/strong><\/p>\r\n\r\n\r\n\r\n
Minimum order quantity depends on the size code, the material and the plating, so it is confirmed with the quotation. Samples and validation parts are available for OEM and distributor evaluation.<\/p>\r\n\r\n\r\n\r\n
Is the nut and sleeve included with the 1JM adapter?<\/strong><\/p>\r\n\r\n\r\n\r\n
No. The 1JM adapter is supplied as the stud only, and the nut and sleeve are ordered separately. Use nut NB200 with sleeve NB500 for metric tube and nut NB200 with sleeve NB300 for inch tube, and note that one stud usually needs one nut and sleeve for the inch end and one for the metric end.<\/p>\r\n\r\n\r\n\r\n
Can a 1JM adapter be used in place of a metric male captive seal part?<\/strong><\/p>\r\n\r\n\r\n\r\n
Only if the port is a metric 60\u00b0 seat port. The two series share a metric thread and look alike at a glance, but the 1JM adapter seals on a machined metric cone while a captive seal part seals through a bonded elastomer washer on a flat face.

Send the part number, the JIC thread, the metric thread, the nut and sleeve requirement for each tube, the material and plating, and the quantity. HENGHUA confirms the match to the printed table, the seal options and the delivery schedule, and quotes the 1JM adapter that fits your circuit.<\/p>\r\n\r\n\r\n\r\n
