What a 1ST-SP Adapter Does<\/h2>\r\n\r\n\r\n\r\n<p>A 1ST-SP adapter is a straight thread adapter with a male end at each side. One end is a JIS gas male stud with a 60\u00b0 cone seat to JIS B 0203, and the other end is a BSPT male taper thread to ISO 7-1.<\/p>\r\n\r\n\r\n\r\n<p>The part exists to join two different port systems in one body. The JIS end screws into a Japanese gas thread port and seals on its 60\u00b0 cone against the mating cone in that port. The BSPT end screws into a taper thread port and seals on the thread flanks, with a sealant applied to the thread. Because both ends are male, the adapter is used where an equipment port and a BSPT female connection have to be brought together without adding a hose assembly or a second adapter.<\/p>\r\n\r\n\r\n\r\n<p>The practical value is direct fit: a JIS gas port that today only accepts imported original parts becomes a BSPT connection point, which is what most repair shops and distributors hold in stock.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">2. 1ST-SP Adapter Specifications<\/h2>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">2.1 Connection 1 &#8211; JIS gas male stud end, 60\u00b0 cone<\/h3>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Thread family: JIS gas thread (parallel pipe thread) to JIS B 0203.<\/li>\r\n<li>Size range in this series: G1\/8&#8243;x28 through G2&#8243;x11.<\/li>\r\n<li>Gender: male stud end with hex flats for wrench engagement.<\/li>\r\n<li>Sealing method: 60\u00b0 cone seat on the stud end, sealing against the matching cone in the mating port.<\/li>\r\n<li>Mating port standard: JIS B 0203 gas thread port with a 60\u00b0 cone seat.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>The cone does the sealing, so the thread is not the sealing element. The stud end must be matched to a port that has the corresponding internal cone; a flat face port with the same thread will not seal on the cone alone, which is the most common sizing mistake on JIS ports in imported machinery.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">2.2 Connection 2 &#8211; BSPT male taper end<\/h3>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Thread family: BSPT taper pipe thread to ISO 7-1, R series.<\/li>\r\n<li>Size range in this series: R1\/8&#8243;x28 through R2&#8243;x11.<\/li>\r\n<li>Gender: male taper end with hex flats for wrench engagement.<\/li>\r\n<li>Sealing method: taper thread sealing on the thread flanks, with a thread sealant applied.<\/li>\r\n<li>Mating port standard: ISO 7-1 BSPT port or BSPT female connection.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>A BSPT end is not interchangeable with a BSP adapter end. BSPP is a parallel thread to ISO 228-1 that seals on a seat or a washer, while BSPT is a taper thread that seals on the thread flanks and needs a sealant. Screwing a BSPT male end into a BSPP female port engages only a few turns and damages the parallel thread, and a BSPP male end in a BSPT port bottoms without sealing.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">2.3 Construction and Materials<\/h3>\r\n\r\n\r\n\r\n<p>Bodies are machined from bar stock on CNC lathes, with the JIS cone cut in the same setup as the thread so that the cone runs true to the thread axis.<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Body material options: carbon steel, 304 stainless steel, 316 stainless steel, brass.<\/li>\r\n<li>Plating options for carbon steel bodies: trivalent chromium zinc plating (Cr3+), zinc-nickel plating.<\/li>\r\n<li>Seal options: the JIS 60\u00b0 cone is a metal-to-metal seat, and the BSPT end uses a thread sealant applied at assembly.<\/li>\r\n<li>Hex features: S1 across flats on the body, per the dimension table in 2.5.<\/li>\r\n<li>Identification: series and size code marked on the body where the size allows.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">2.4 Pressure and Temperature<\/h3>\r\n\r\n\r\n\r\n<p>The JIS 60\u00b0 cone end is a metal seat and carries no elastomer. Service temperature is therefore governed by the body material and by the sealant used on the taper end, and the metal seat avoids the temperature limit that a rubber seal imposes at that joint.<\/p>\r\n\r\n\r\n\r\n<table>\r\n<thead>\r\n<tr>\r\n<th>Material<\/th>\r\n<th>Typical service note<\/th>\r\n<\/tr>\r\n<\/thead>\r\n<tbody>\r\n<tr>\r\n<td>Carbon steel with zinc plating<\/td>\r\n<td>General hydraulic service<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>304 \/ 316 stainless steel<\/td>\r\n<td>Corrosive and offshore service<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Brass<\/td>\r\n<td>Non-sparking and some water service<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n\r\n\r\n\r\n<p>Working pressure is not a single figure for the whole series.

How to Read a 1ST-SP Part Number<\/h2>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li><strong>1ST<\/strong>: series prefix for a straight adapter with a JIS gas male 60\u00b0 cone end and a BSPT male end.<\/li>\r\n<li><strong>-SP suffix<\/strong>: marks the taper thread family in this range, so a part number ending in -SP always carries a BSPT end and requires a thread sealant.<\/li>\r\n<li><strong>First size code<\/strong> (JIS gas end): 02 = G1\/8&#8243;x28, 04 = G1\/4&#8243;x19, 06 = G3\/8&#8243;x19, 08 = G1\/2&#8243;x14, 12 = G3\/4&#8243;x14, 16 = G1&#8243;x11, 20 = G1.1\/4&#8243;x11, 24 = G1.1\/2&#8243;x11, 32 = G2&#8243;x11.<\/li>\r\n<li><strong>Second size code<\/strong> (BSPT end): 02 = R1\/8&#8243;x28, 04 = R1\/4&#8243;x19, 06 = R3\/8&#8243;x19, 08 = R1\/2&#8243;x14, 12 = R3\/4&#8243;x14, 16 = R1&#8243;x11.<\/li>\r\n<li><strong>Single code<\/strong>: one number only, used where the two ends follow the standard coded pair for that size.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>Worked example: <strong>1ST-06-08SP<\/strong>. The prefix 1ST fixes the series and the -SP suffix confirms the taper end. The first code 06 sets the JIS gas end at G3\/8&#8243;x19 with a 60\u00b0 cone to JIS B 0203. The second code 08 sets the taper end at R1\/2&#8243;x14 to ISO 7-1. Reading the table, the adapter measures A 18 mm, B 20 mm, L 46 mm and S1 22 mm across the body hex. Quote 1ST-06-08SP with the material and plating to place the line.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">4. Installation and Fitment<\/h2>\r\n\r\n\r\n\r\n<p>Fitment of a thread adapter starts with identification, because the two ends look similar in the hand. The JIS gas end and the BSPT end are both pipe threads, but one is parallel with a cone seat and the other is tapered.<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Check the cone on the JIS end and the cone in the port: they must be clean, free of burrs and undamaged. A scored cone will leak no matter how tight the joint is.<\/li>\r\n<li>Apply a thread sealant to the BSPT end only, and leave the first thread dry so that sealant does not enter the system. Never apply sealant to the JIS cone.<\/li>\r\n<li>Bring the adapter in by hand. The JIS end should turn freely until the cone contacts its seat; the BSPT end will tighten progressively as the taper engages.<\/li>\r\n<li>Hold the body hex S1 with one wrench and tighten the BSPT side with a second wrench. Torque practice is snug contact first and then a controlled tightening angle. The figure depends on thread size and material, so it is confirmed per order rather than quoted as one number for all sizes.<\/li>\r\n<li>Do not over-tighten the taper end to stop a leak. Over-tightening splits the female port and expands the male thread, after which no sealant will hold.<\/li>\r\n<li>Re-check both joints after the machine reaches working temperature, and support the connected pipe or hose so that vibration is not carried into the adapter.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>Common fitment errors and their symptoms: a BSPP hose end screwed onto the BSPT end engages only a few turns and leaks at the first pressure cycle because the parallel female thread cannot seal on the taper flanks. Sealant applied to the JIS cone holds the cone off its seat, producing a leak that appears to come from the thread. Reusing a taper joint without fresh sealant on cleaned threads gives a joint that weeps as soon as it is disturbed.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">5. Applications and Industries<\/h2>\r\n\r\n\r\n\r\n<p>Application tags: hydraulic systems, industrial equipment, construction machinery, agriculture, material handling, marine, oil and gas, water jetting.<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li><strong>Japanese equipment aftermarket.<\/strong> Japanese-built construction machinery, machine tools, injection moulding machines and forklifts use JIS gas thread ports on pumps, valves, cylinders and manifolds. When these machines are serviced outside Japan, the local hose and fitting supply typically follows BSPT or BSP, so a JIS port has to be converted to the thread the workshop actually stocks. The 1ST-SP adapter is the part that makes that conversion at the port, with no hose rework.<\/li>\r\n<li><strong>Spare parts distribution.<\/strong> A distributor holding BSPT male hose ends and BSPT fittings can support imported Japanese machines by stocking one family of JIS-to-BSPT adapters instead of a full range of JIS hose assemblies.<\/li>\r\n<li><strong>Repair and replacement.<\/strong> When an original JIS adapter is damaged, the replacement is chosen by reading the two thread callouts off the old part and matching them in the table above, rather than by part number from another maker.<\/li>\r\n<li><strong>Machines re-piped locally.<\/strong> Where a machine is re-piped with locally available BSPT hose, the JIS ports on its original components still need an interface. This series keeps that interface to one short part per port.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">6. Replacement and Cross-Reference Guide<\/h2>\r\n\r\n\r\n\r\n<p>Cross-reference any BSP adapter or JIS gas part by standard and sealing method, never by another maker&#8217;s catalogue number. Three measurements identify the correct replacement: the thread, the cone, and the direction of the taper.<\/p>\r\n\r\n\r\n\r\n<ol class=\"wp-block-list\">\r\n<li><strong>Thread size and pitch.<\/strong> Measure the outside diameter and the threads per inch of both ends. A JIS gas end at 9.53 mm with 28 threads per inch is G1\/8&#8243;x28; a BSPT end is matched by its R size and pitch, for example R3\/8&#8243;x19.<\/li>\r\n<li><strong>Cone form.<\/strong> Confirm that the JIS side is a 60\u00b0 cone stud end. If the port has a flat face and the old part carried a washer, the application needs a different sealing method rather than this series.<\/li>\r\n<li><strong>Which end is tapered.<\/strong> A taper end is identified by the change in diameter along the thread: the BSPT side is larger at the body and smaller at the nose. A parallel end keeps the same diameter over the full thread length.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<p>Related families in the same HENGHUA British Adapters range, by function: 1T-SP covers a BSPT male end to a BSP male end; 1T9-SP is the 90\u00b0 elbow version of the same connection; 1ST9-SP is the 90\u00b0 elbow version of this series; 1BT-SP covers a BSP male 60\u00b0 seat end to a BSPT male end; 5T-SP covers BSPT male to BSPT female; and 4T-SP is the BSPT male plug for closing a taper port.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">7. Ordering, Packaging and Delivery<\/h2>\r\n\r\n\r\n\r\n<p>To place a quotation request, send these six items: series code, full part number, the thread size of each end, the body material, the plating, and the annual or first-order quantity.<\/p>\r\n\r\n\r\n\r\n<p>Example of a complete inquiry line: series 1ST-SP, part number 1ST-06-08SP, JIS gas end G3\/8&#8243;x19 with 60\u00b0 cone to JIS B 0203, BSPT end R1\/2&#8243;x14 to ISO 7-1, carbon steel body with trivalent chromium zinc plating, 300 pieces.<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li><strong>Packaging.<\/strong> Parts are bagged and cartoned in quantities suited to distributor shelf handling, with larger sizes cartoned loose in single size groups. Carton labels carry the series code, the part number and the quantity.<\/li>\r\n<li><strong>Labelling.<\/strong> Neutral labelling is available for distributors who re-label under their own brand, and customer label artwork can be applied where supplied.<\/li>\r\n<li><strong>Samples.<\/strong> Single pieces or small sample sets can be supplied for fit validation.

Thread gauge checking is the only reliable way to verify a taper end, because a taper has no single diameter to measure.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">8. FAQ<\/h2>\r\n\r\n\r\n\r\n<p><strong>Q1. What is the difference between BSPP and BSPT, and can they be interchanged?<\/strong> BSPP is a parallel pipe thread to ISO 228-1 and seals on a seat or a washer, not on the thread. BSPT is a taper pipe thread to ISO 7-1 that seals on the thread flanks and needs a thread sealant. They must not be interchanged: a BSPT male end in a BSPP port engages only a few turns and damages the parallel thread, while a BSPP male end in a BSPT port bottoms without sealing. On this page the -SP suffix always marks the taper side.<\/p>\r\n\r\n\r\n\r\n<p><strong>Q2. What is the difference between a 60\u00b0 cone seat and a bonded seal, and which should I choose?<\/strong> The 60\u00b0 cone seat seals where a machined cone on the stud end meets the matching cone in the port. A bonded seal seals where a metal washer with a bonded elastomer ring is compressed against a flat port face. The JIS gas end of this series uses the 60\u00b0 cone, so the port must have the matching internal cone. If the port face is flat, choose a series that carries a bonded seal rather than this one.<\/p>\r\n\r\n\r\n\r\n<p><strong>Q3. How do I identify the correct 1ST-SP adapter size?<\/strong> Measure the outside diameter and pitch of both ends. The JIS gas end is matched to the G size and pitch, for example G1\/2&#8243;x14, and the taper end is matched to the R size and pitch, for example R1\/2&#8243;x14. Confirm that the first end is a JIS gas 60\u00b0 cone part and not a BSPP thread of the same nominal size, then match the pair in the table. Any pair that is not listed can be produced to drawing as a special.<\/p>\r\n\r\n\r\n\r\n<p><strong>Q4. What seal material should I select for my fluid and temperature?<\/strong> The JIS 60\u00b0 cone end is a metal-to-metal seat and uses no elastomer, so there is no seal to select for that joint. Selection concerns the BSPT end, where the thread sealant has to suit the fluid: use a hydraulic-rated sealant that is compatible with the oil in the system, and keep it off the cone. Body material is chosen for the environment, with 304 or 316 stainless steel for corrosive and offshore service.<\/p>\r\n\r\n\r\n\r\n<p><strong>Q5. How is the working pressure determined?<\/strong> Working pressure is not one figure for the whole series. It depends on the thread size, the wall thickness of the body at that size, the sealing method and the material grade, and it is confirmed per order by HENGHUA engineering. Taper thread joints also depend on the condition of the mating port and the sealant used. State the system and peak pressures with the inquiry so the size and grade can be confirmed for the duty.<\/p>\r\n\r\n\r\n\r\n<p><strong>Q6. What is the minimum order quantity and can I get samples?<\/strong> Sample quantities can be supplied for fit validation before a production order. The minimum order quantity depends on the size, the material grade and the plating selected and is confirmed in the quotation. Send the part numbers, material and expected annual quantity in one inquiry so that the sample set and the production release can be quoted together.<\/p>\r\n\r\n\r\n\r\n<p><strong>Q7. Can I use a BSPP hose end on the taper side of this adapter?<\/strong> No. The taper end needs a BSPT female connection so that the flanks can deform and seal. A BSPP female end is parallel, so it cannot seal on the taper flanks and will leak. If the hose end you hold is BSPP, use a series with a parallel male end instead of the -SP version.<\/p>\r\n\r\n\r\n\r\n<p><strong>Q8. Why do Japanese machines need this adapter at all?<\/strong> JIS gas threads to JIS B 0203 are widely used on Japanese-built hydraulic equipment, and they are not interchangeable with BSPP or BSPT even when the nominal size is the same. Outside Japan, workshops usually stock BSPT and BSP fittings, so a JIS port has to be converted at the port to reach the hose end on the shelf. That conversion is what this series provides.<\/p>\r\n\r\n\r\n\r\n<p>Browse the full <a href=\"https:\/\/www.henghuahose.com\/de\/product-category\/hydraulic-adapters\/\" target=\"_blank\" rel=\"noopener\">Hydraulic Adapters<\/a> range for the complete family, or <a href=\"https:\/\/www.henghuahose.com\/de\/contact\/\" target=\"_blank\" rel=\"noopener\">contact us<\/a> to request a quote, mill test reports, and samples.<\/p>","protected":false},"excerpt":{"rendered":"<p>The 1ST-SP adapter is a straight steel hydraulic adapter that joins a JIS gas male 60\u00b0 cone end to a BSPT male taper end.
