The 1JB-WD 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 BSP male end fitted with a captive seal. It is the hydraulic conversion adapter used where an SAE inch tube line has to meet a BSP port whose joint is closed on a flat face by an elastomer washer rather than on the thread.<\/p>\r\n\r\n\r\n\r\n
Both ends must match their mating port exactly, because that match is the precondition for eliminating leakage at the conversion point. The BSP end of this male adapter does not seal on its thread at all: the G thread to ISO 228-1 is a parallel pipe thread where pressure tightness is not made on the threads, so the captive seal closes the joint against the flat face of the port.<\/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 BSP male end with a captive seal that is compressed against the flat face of the mating port. The captive seal is a bonded seal, an elastomer element held in a metal carrier and seated in a groove on the stud so that it cannot be lost and cannot walk out of position during tightening.<\/p>\r\n\r\n\r\n\r\n
Core Advantages<\/h2>\r\n\r\n\r\n\r\n
\r\n
One piece carries an SAE J514 inch thread and a BSP G thread, so an inch line meets a BSP flat-face port without an extra reducer.<\/li>\r\n\r\n\r\n\r\n
The BSP end seals by captive seal on a flat face, so the joint does not depend on thread interference or on a sealant.<\/li>\r\n\r\n\r\n\r\n
Captive seal held in its own groove, so the washer stays on the stud during handling, storage and assembly.<\/li>\r\n\r\n\r\n\r\n
Metal-to-metal 74\u00b0 cone at the JIC end, with no elastomer in the cone sealing path.<\/li>\r\n\r\n\r\n\r\n
BSP thread sizes from G1\/8″x28 up to G1.1\/2″x11, against JIC sizes from 7\/16″x20 to 1.7\/8″x12.<\/li>\r\n\r\n\r\n\r\n
Carbon steel with trivalent chromium zinc plating, or 304 \/ 316 stainless steel for corrosive service.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
1. What a 1JB-WD Adapter Does<\/h2>\r\n\r\n\r\n\r\n
A 1JB-WD adapter is a straight stud with a JIC 74\u00b0 cone male end on one side and a BSP male captive seal end on the other. It connects a tube assembly terminated with a JIC 74\u00b0 cone nut and sleeve to a port whose sealing surface is a flat face and whose thread is a BSP parallel thread.<\/p>\r\n\r\n\r\n\r\n
This JIC adapter does one job: it moves fluid between an SAE inch port and a BSP port without changing direction, while changing the sealing method at the same time. The E column is the SAE J514 JIC 74\u00b0 cone end, printed in the inch style such as 9\/16\"X18<\/code>, and the F column is the BSP captive seal end, printed as a G thread such as G1\/4\"X19<\/code>. The CAPTIVE SEAL column prints the seal reference for that thread, such as WD-B04<\/code>.<\/p>\r\n\r\n\r\n\r\n
The difference between this series and a BSP male 60\u00b0 seat part is the second sealing surface, not the thread: the 60\u00b0 seat part seats a machined cone in the port seat, while this version seats an elastomer washer against a flat face. Section 6 sets out how to tell the two apart.<\/p>\r\n\r\n\r\n\r\n
2. 1JB-WD Specifications<\/h2>\r\n\r\n\r\n\r\n

Mating port standard: a BSP port with a flat sealing face and a spotface wide enough to accept the captive seal washer, of the type covered by the bonded seal port described in ISO 1179.<\/li>\r\n<\/ul>\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 BSP captive seal end, with the CAPTIVE SEAL column giving the seal reference. The two mirrored blocks above map one end to the tube side and the other to the flat-face port.<\/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 inch thread, the BSP thread, the 74\u00b0 cone and the seal groove are turned in one setup so the cone and the groove stay square to their threads.<\/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 performance is confirmed per order rather than published as a series figure.<\/li>\r\n\r\n\r\n\r\n
Seal material options: NBR, FKM (Viton-type) and EPDM for the captive seal. The 74\u00b0 cone at the JIC end is metal-to-metal and carries no elastomer.<\/li>\r\n\r\n\r\n\r\n
Each thread form is produced to its own port standard, and the cone and seal face are 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 55 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 1JB-WD 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, and is confirmed per order by HENGHUA engineering.<\/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. In this series these figures govern the captive seal at the BSP end, because the 74\u00b0 cone end has no elastomer in its sealing path.<\/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 or offshore service.<\/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 1JB-WD series; lengths 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
PART NO.<\/strong> – the HENGHUA part number: the prefix 1JB<\/code>, the size codes and the WD<\/code> suffix that marks the captive seal end.<\/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 3\/4\"X16<\/code>.<\/li>\r\n\r\n\r\n\r\n
F<\/strong> – the thread of connection 2, the BSP captive seal end, printed as a G thread with its pitch, for example G1\/2\"X14<\/code>.<\/li>\r\n\r\n\r\n\r\n
CAPTIVE SEAL (F END)<\/strong> – the captive seal reference for the BSP end, for example WD-B08<\/code>, identifying the seal that belongs to that thread size.<\/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 BSP captive seal 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 BSP thread and the captive seal reference are 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<\/th>\r\n
BSP threads at the F end<\/th>\r\n<\/tr>\r\n<\/thead>\r\n
Nut and sleeve are ordered separately.<\/strong> The 1JB-WD stud does not include them. Use nut NB200 with sleeve NB500 for metric tube and with sleeve NB300 for inch tube.<\/p>\r\n\r\n\r\n\r\n
3. How to Read a 1JB-WD Part Number<\/h2>\r\n\r\n\r\n\r\n
A 1JB-WD part number has three elements: the series prefix, one or two size codes, and the WD<\/code> suffix that marks the captive seal end.<\/p>\r\n\r\n\r\n\r\n
The prefix 1JB<\/code> identifies the geometry: a straight stud with a JIC 74\u00b0 cone male end and a BSP male end. The WD<\/code> suffix changes the sealing method, because the BSP end now seals through a captive elastomer washer on a flat face instead of through a machined 60\u00b0 seat. Other prefixes cover the metric end, the NPT male end and other conversion families.<\/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 BSP end, taken from the G thread designation. Where one size code is printed, such as 1JB-04WD<\/code>, the row pairs that JIC size with the BSP size of matching rank; where two codes are printed, the part steps between two sizes. 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: 1JB-08WD.<\/strong><\/p>\r\n\r\n\r\n\r\n
\r\n
1JB<\/code> – straight stud, JIC 74\u00b0 cone male to BSP male captive seal.<\/li>\r\n\r\n\r\n\r\n
08<\/code> – connection 1 is the SAE J514 size with a 3\/4″x16 thread.<\/li>\r\n\r\n\r\n\r\n
WD<\/code> – the BSP end seals through a captive bonded seal on a flat face.<\/li>\r\n\r\n\r\n\r\n
From the table: the BSP thread is G1\/2″x14, the seal reference is WD-B08, A is 16.7 mm, B is 14 mm, L is 43.5 mm and S1 is 27 mm.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
A buyer ordering 1JB-08WD therefore receives a male adapter whose JIC end takes a 3\/4″x16 tube assembly and whose BSP end screws into a G1\/2″ flat-face port. Check that the port face is flat and wide enough for the seal washer, because a port with a 60\u00b0 internal seat gives this end no sealing surface.<\/p>\r\n\r\n\r\n\r\n
4. Installation and Fitment<\/h2>\r\n\r\n\r\n\r\n
The two ends of a 1JB-WD adapter are tightened by different rules. The JIC end is a cone joint and is tightened until the cone seats metal-to-metal. The BSP end is a flat-face joint and is tightened only until the captive seal is compressed against the port face. HENGHUA does not print a single torque figure for this hydraulic adapter, because the correct tightening depends on the mating port, the tube material and the wall thickness.<\/p>\r\n\r\n\r\n\r\n
Cone seat handling: keep the 74\u00b0 cone and the mating JIC seat clean and free of nicks. Wipe the cone with a lint-free cloth and inspect it under good light. An overtightened cone is deformed and must be replaced.<\/p>\r\n\r\n\r\n\r\n
Captive seal handling: check that the washer sits squarely in its groove before starting the thread, and replace the seal if it is cut, swollen or hardened. A bonded seal that has taken a compression set will not seal again.<\/p>\r\n\r\n\r\n\r\n
Thread preparation: neither thread is the sealing element in this series, so do not wrap the threads with thread tape and do not use sealant as a leak cure. Sealant on the flat face can push the washer off centre.<\/p>\r\n\r\n\r\n\r\n
Contamination control: cap open ends before storage, because debris on the flat face stops the seal from bedding.<\/p>\r\n\r\n\r\n\r\n
Alignment: bring the tube squarely to the cone end and the body squarely to the flat-face port, because a body pulled sideways loads the captive seal unevenly.<\/p>\r\n\r\n\r\n\r\n
Reuse policy: a stud body with an undamaged cone and groove can be reused; the nut, the sleeve and the captive seal are replaced at every rebuild.<\/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
Fitting a captive seal part into a port with a 60\u00b0 internal seat. Symptom: the end bottoms without compressing the seal and weeps from first pressure.<\/li>\r\n\r\n\r\n\r\n
Fitting a 60\u00b0 seat part into a flat-face port. Symptom: the cone never touches a seat, so the joint leaks and the seal face is marked.<\/li>\r\n\r\n\r\n\r\n
Overtightening the flat-face end to stop a seep. Symptom: a crushed captive seal, a distorted washer 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 BSP end matches the port thread and seal reference.<\/li>\r\n\r\n\r\n\r\n
Inspect the cone, the seal groove and the port face for nicks, corrosion and previous overtightening marks.<\/li>\r\n\r\n\r\n\r\n
Check the captive seal for cuts and set, and confirm it sits squarely in its groove.<\/li>\r\n\r\n\r\n\r\n
Fit the nut and sleeve to the JIC tube, then bring the tube square to the cone end by hand.<\/li>\r\n\r\n\r\n\r\n
Run the JIC nut up by hand and tighten in stages until the cone seats; run the BSP end in until the seal is compressed.<\/li>\r\n\r\n\r\n\r\n
Pressurise the circuit, check both ends for weeping, and re-check 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.<\/p>\r\n\r\n\r\n\r\n
Cross-standard equipment integration.<\/strong> Imported machinery frequently arrives with a BSP port face on the manifold and an SAE inch tube line on the machine. This hydraulic conversion adapter provides the interface the two sides need, and rows such as 1JB-08WD step between a smaller JIC line and a larger BSP port without a second reducer. A flat-face BSP port has no internal cone, so it can only be served by a flat-face sealing method such as this captive seal end.<\/p>\r\n\r\n\r\n\r\n
Repair and replacement.<\/strong> Maintenance crews fit this series when a damaged inch tube end or a leaking BSP port stud has to be replaced on site. The part arrives complete because the captive seal sits on the stud to the reference printed in the table.<\/p>\r\n\r\n\r\n\r\n
High-pressure test benches.<\/strong> Test rigs need interfaces that can be broken and remade many times during a programme. The captive seal end makes that cycle predictable, because the sealing element is a washer that is renewed.<\/p>\r\n\r\n\r\n\r\n
OEM assembly lines.<\/strong> On a production line the 1JB-WD adapter is supplied to a drawing-based specification with material, plating and seal compound fixed per programme.<\/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, thread size, seat angle and seal type all match.<\/p>\r\n\r\n\r\n\r\n
A 1JB-WD adapter is a JIC adapter with an SAE J514 74\u00b0 cone stud at one end and a BSP captive seal stud at the other. It does not interchange with a JIC 37\u00b0 flare fitting, which seals on a 37\u00b0 conical flare face, or with an ORFS fitting, which seals a flat face against an O-ring in the fitting face under SAE J1453. The closest lookalike is the BSP male part machined with a 60\u00b0 internal seat: same G thread, similar hex, different seat.<\/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 at both ends.<\/strong> Measure the outside diameter and the pitch of each thread and record them separately. A 3\/4″ end measures about 19.1 mm outside diameter with 16 threads per inch, while a G1\/2″ end measures about 20.9 mm with 14 threads per inch: similar diameters, no interchange.<\/li>\r\n\r\n\r\n\r\n
Sealing surface at the BSP end.<\/strong> Look for the captive seal groove and washer. A machined cone instead of a groove means a 60\u00b0 seat part, not this series.<\/li>\r\n\r\n\r\n\r\n
Port face.<\/strong> Check the port the part came out of: a flat face with a spotface wide enough for the washer confirms a captive seal joint, while an internal cone confirms a 60\u00b0 seat joint.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n
Where one of the ports is a taper pipe thread such as BSPT or NPT, a cross standard hydraulic conversion adapter for that thread family is the correct part. Record the measurements with the part number and HENGHUA can match the replacement, including the seal reference.<\/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: 1JB-WD<\/code>.<\/li>\r\n\r\n\r\n\r\n
Full part number, for example 1JB-10-12WD, taken from table 2.5.<\/li>\r\n\r\n\r\n\r\n
Thread sizes for the JIC end and the BSP end, plus the seal reference from the CAPTIVE SEAL column.<\/li>\r\n\r\n\r\n\r\n
Nut and sleeve requirement for the inch tube (nut NB200 with sleeve NB300), ordered separately from the stud.<\/li>\r\n\r\n\r\n\r\n
Seal compound for the captive seal (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 and seal reference. Sample orders: validation and first-article parts are available for OEM programmes, including specials outside the printed table.<\/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, the seal compound and the quantity. As a hydraulic adapter manufacturer and 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. The 1JB-WD series is on the JIC 74\u00b0 cone side of SAE J514, with a captive seal at the BSP end.<\/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. The BSP end of this series is a parallel thread under ISO 228-1, a third family, so a taper pipe port 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 1JB-WD adapter 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, F and CAPTIVE SEAL columns of table 2.5. When the JIC thread, the BSP thread and the seal reference all match a printed row, that row is the correct part number, so do not order a washer by thread size alone.<\/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-based fluids, choose EPDM, with a range of approximately -40\u00b0C to +120\u00b0C. In this series the choice applies to the captive seal, not the metal cone end.<\/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 and the material selected, and is confirmed per order by HENGHUA engineering.<\/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, the plating and the seal compound, so it is confirmed with the quotation. Samples are available for OEM evaluation.<\/p>\r\n\r\n\r\n\r\n
Is the captive seal supplied with the 1JB-WD adapter?<\/strong><\/p>\r\n\r\n\r\n\r\n
The captive seal sits in a groove on the stud and is supplied with the part to the reference printed in the CAPTIVE SEAL column, which is why that column lists a reference for every row. On a rebuild the seal is replaced rather than reused.<\/p>\r\n\r\n\r\n\r\n
Can I use this series in a BSP port that has a 60\u00b0 internal seat?<\/strong><\/p>\r\n\r\n\r\n\r\n
No. A port with a 60\u00b0 internal seat needs a stud with a machined 60\u00b0 seat on the BSP end. In a captive seal joint the elastomer washer closes against a flat face, while in a 60\u00b0 seat joint the metal cone closes against the seat, so the ends are not interchangeable even when the threads match.<\/p>\r\n\r\n\r\n\r\n
Send your requirement to HENGHUA<\/strong><\/p>\r\n\r\n\r\n\r\n
Send the part number, the JIC thread, the BSP thread and seal reference, 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 1JB-WD adapter that fits your circuit.<\/p>\r\n\r\n\r\n\r\n
