There is no male thread, no cone and no O-ring: the part is a fully tapped tee that joins three male NPT pipe threads at a junction and lets one line split into two. Its duties are the same as the straight version of the family, with one addition: it adds a third tapped port at 90\u00b0 to the through line, so a gauge, a drain or a second line can be taken off a pipe-threaded circuit without a separate junction block.<\/p>\r\n\r\n\r\n\r\n<p>All three tapped ports must match their mating male threads exactly in thread form, nominal size and pitch, because that match is the precondition for eliminating leakage at the conversion point. A GN-PK adapter with the wrong taper thread family will start on the mating thread and still weep under pressure.<\/p>\r\n\r\n\r\n\r\n<p>Sealing principle of this series: pressure tightness is made on the thread flanks as each male taper is drawn into the tapped taper of the tee. A tapped taper thread of this type seals on the thread flanks and needs a sealant applied to the mating male thread, or an NPTF dryseal thread pair per SAE J476. This series does not seal on a 37\u00b0 flare, on a 74\u00b0 cone, on an O-ring face, on an elastomeric seat or on a four-bolt flange.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">Core Advantages<\/h2>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Tee body with three tapped ports, so one line can be split into two without a separate junction block.<\/li>\r\n\r\n\r\n\r\n<li>Internal NPT taper thread at all three ports, so the part is used where every mating connection is a male pipe thread.<\/li>\r\n\r\n\r\n\r\n<li>Nine printed rows, Z1\/8&#8243;X27 through Z2&#8243;X11.5, in a symmetric equal-ended range with one hex size per row.<\/li>\r\n\r\n\r\n\r\n<li>Threads gauged at all three ports against the drawing before packing.<\/li>\r\n\r\n\r\n\r\n<li>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<h2 class=\"wp-block-heading\">1. What a GN-PK Adapter Does<\/h2>\r\n\r\n\r\n\r\n<p>A GN-PK adapter joins three male NPT pipe ends in one body. The two ports at the ends of the horizontal run are marked E on the left and G on the right, and the third port is marked F on the vertical branch at the top of the body. What enters the E end leaves through G and F, and what enters F leaves through E and G, so the part divides or combines flow at a tee junction.<\/p>\r\n\r\n\r\n\r\n<p>Each port is a tapped thread. That means the thread is cut inside the body: the male pipe thread of the mating part is screwed into it, and the seal is formed on the flanks of that male thread as it is drawn into the taper. Nothing on the outside of the tee seals, which is why the sealant is applied to the mating male thread. The adapter supplies the thread, the mating male part supplies the seal.<\/p>\r\n\r\n\r\n\r\n<p>The geometry of a tee matters as much as the thread. The run is the straight flow path through the body, and on this series the run ports are E on the left and G on the right. The branch is the port that leaves the run at 90\u00b0, and on this series the branch port is F at the top. A branch tee of the same family would carry a different port arrangement, so the run and branch identity of each port must be confirmed before a replacement is ordered.<\/p>\r\n\r\n\r\n\r\n<p>The first duty of the tee is to create a junction in a pipe-threaded line. Where a circuit needs a pressure take-off, a drain line or a parallel branch, a tapped tee in the existing line makes the connection without a separate manifold or a welded boss. The two run ports continue the original line and the branch serves the new function.<\/p>\r\n\r\n\r\n\r\n<p>The second duty is a junction between three male pipe threads without adding adapters. Because all three ports are tapped, three male pipe fittings screw directly into the body and no male end is wasted. That keeps the assembly short, keeps the number of joints to three and leaves one hex on the body for holding it while any port is made up.<\/p>\r\n\r\n\r\n\r\n<p>Because there is no seat angle and no elastomer in this series, there is nothing to deform but the threads themselves. Thread condition and the sealant therefore govern the result, at all three ports and at every assembly.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">2. GN-PK Specifications<\/h2>\r\n\r\n\r\n\r\n<p>The three ports are presented below as two mirrored blocks: one for the run ends E and G, one for the branch end F. All three ports of this female adapter are the same type and the same size in every printed row.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">2.1 Connection 1 &#8211; NPT female taper thread, E and G ports on the run<\/h3>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Thread standard and family: American tapered pipe thread NPT to ANSI\/ASME B1.20.1, with NPTF dryseal threads to SAE J476 as the pressure-tight option.<\/li>\r\n\r\n\r\n\r\n<li>Thread size range available at E and G: Z1\/8&#8243;X27 through Z2&#8243;X11.5, in the steps printed in table 2.5.<\/li>\r\n\r\n\r\n\r\n<li>Gender: female, an internal tapped thread on the horizontal run, one at each end.<\/li>\r\n\r\n\r\n\r\n<li>Sealing method: metal-to-metal contact on the thread flanks of the mating male thread, with a sealant applied by the installer.<\/li>\r\n\r\n\r\n\r\n<li>Mating connection standard: a male NPT or NPTF pipe thread of the same nominal size and pitch, such as a hose tail, nipple or male stud.<\/li>\r\n\r\n\r\n\r\n<li>Quantity: two ports, one at each end of the run, both the same size in every printed row.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">2.2 Connection 2 &#8211; NPT female taper thread, F port on the branch<\/h3>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Thread standard and family: American tapered pipe thread NPT to ANSI\/ASME B1.20.1, with NPTF to SAE J476 as the dryseal option.<\/li>\r\n\r\n\r\n\r\n<li>Thread size range available at F: the same nine steps as connection 1, from Z1\/8&#8243;X27 to Z2&#8243;X11.5.<\/li>\r\n\r\n\r\n\r\n<li>Gender: female, an internal tapped thread on the vertical branch.<\/li>\r\n\r\n\r\n\r\n<li>Sealing method: metal-to-metal contact on the thread flanks of the mating male thread, with a sealant applied by the installer.<\/li>\r\n\r\n\r\n\r\n<li>Mating connection standard: a male NPT or NPTF pipe thread of the same nominal size and pitch.<\/li>\r\n\r\n\r\n\r\n<li>Quantity: one port, on the branch at 90\u00b0 to the run.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>All three ports of this female adapter are tapped threads; only the body geometry distinguishes the run from the branch. There is no male end and no seat anywhere on the part.<\/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>The body is machined from bar stock on CNC lathes as a tee, then drilled and tapped with the NPT taper at each of the three ports, with a hex formed across the body.<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Body material: carbon steel as standard; 304 stainless steel, 316 stainless steel or brass on request.<\/li>\r\n\r\n\r\n\r\n<li>Plating: 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<li>Seal material: this thread adapter carries no elastomer, no O-ring and no bonded washer. Pressure tightness comes from the thread pair plus the sealant chosen by the installer.<\/li>\r\n\r\n\r\n\r\n<li>Machining process: bar-stock turning, drilling on two axes, NPT taper tapped and gauged at all three ports, then deburred.<\/li>\r\n\r\n\r\n\r\n<li>Hex feature: a single hex (S1) across the body, from 16 mm to 70 mm across flats depending on size. There is no bulkhead feature and no swivel in this series.<\/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>Working pressure for a GN-PK adapter is not set by the series code. It is governed by the thread size, the wall thickness of the tee body, the sealing method and the material selected, and it is limited by the three mating male threads. 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<p>Temperature is a question of the body material and the sealant rather than of an elastomer, because the part contains none. Published material ranges of the elastomers used elsewhere in the same circuit are approximately -30\u00b0C to +100\u00b0C for NBR, -20\u00b0C to +200\u00b0C for FKM (Viton-type) and -40\u00b0C to +120\u00b0C for EPDM.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">2.5 Part Number and Dimension Table<\/h3>\r\n\r\n\r\n\r\n<p>The table below is the complete printed size range of the GN-PK series.

How to Read a GN-PK Part Number<\/h2>\r\n\r\n\r\n\r\n<p>A GN-PK part number has three elements: the family prefix, the size code and the tee suffix.<\/p>\r\n\r\n\r\n\r\n<p>The prefix <code>GN<\/code> identifies the family: the tapped female tee adapter, with an internal NPT taper thread at all three ports. In the same catalogue the letter G marks the female pipe thread family and the following number marks the body type. The suffix <code>PK<\/code> marks the tee variant of that family, so the complete code reads as the tee version of the tapped female NPT adapter.<\/p>\r\n\r\n\r\n\r\n<p>The size code is the pipe dash number: 02 means 1\/8&#8243;, 04 means 1\/4&#8243;, 06 means 3\/8&#8243;, 08 means 1\/2&#8243;, 12 means 3\/4&#8243;, 16 means 1&#8243;, 20 means 1.1\/4&#8243;, 24 means 1.1\/2&#8243; and 32 means 2&#8243;. One size code covers all three ports, so every port takes the same male pipe thread.<\/p>\r\n\r\n\r\n\r\n<p><strong>Worked example: GN-08PK.<\/strong><\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li><code>GN<\/code> &#8211; tapped female tee body of the NPT female family.<\/li>\r\n\r\n\r\n\r\n<li><code>08<\/code> &#8211; size code 8, which is the 1\/2&#8243; nominal pipe size.<\/li>\r\n\r\n\r\n\r\n<li><code>PK<\/code> &#8211; tee variant suffix.<\/li>\r\n\r\n\r\n\r\n<li>From the table: E, F and G are all Z1\/2&#8243;X14, A, B and C are 31 mm and the hex S1 is 27 mm.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>A buyer ordering GN-08PK therefore receives a tapped tee that couples a 1\/2&#8243; male pipe thread at each end of the run and a 1\/2&#8243; male pipe thread at the branch, with a 27 mm hex for holding the body. If a different suffix appears on your drawing, quote the full part number including it.<\/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>An NPT joint is made by drawing a tapered male thread into a tapered female thread until the flanks lock, so tightening is a feel-and-angle operation rather than a flat torque figure. HENGHUA does not publish a single torque figure for the series. Follow the port maker&#8217;s recommendation, or confirm the figure with HENGHUA per order.<\/p>\r\n\r\n\r\n\r\n<p><strong>Sealant, not tape fragments.<\/strong> Thread preparation matters more on this NPT adapter than on a flared or O-ring family, because the thread is the seal at all three ports. A tapped taper thread seals on the thread flanks and needs a sealant: clean each male thread, dry it, and apply a sealant compatible with the fluid and the system temperature. Leave the first thread at each entry clean so no tape fragment can enter the circuit.<\/p>\r\n\r\n\r\n\r\n<p><strong>Clock the branch first.<\/strong> Decide which way the branch has to point before the run joints are tightened, because the taper lets the tee be rotated as it is made up. Bring the two run male threads in finger-tight, turn the body until the branch faces the required direction, then hold the hex S1 and snug both run joints in turn.<\/p>\r\n\r\n\r\n\r\n<p><strong>Contamination and reuse.<\/strong> Cap all three tapped ports before storage, because debris that reaches the thread flanks scores them. The body can be reused if all three tapped threads are undamaged, but each joint is made up again with fresh sealant because the old sealant no longer fills the flanks.<\/p>\r\n\r\n\r\n\r\n<p>Common fitment errors and their symptoms:<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Forcing an NPT male thread into a BSPT tapped end.

Applications and Industries<\/h2>\r\n\r\n\r\n\r\n<p>Application tags for this series: hydraulic systems, water jetting, oil and gas, industrial equipment, construction machinery, agriculture, marine, material handling. A tee adapter of this type is selected by its three pipe threads and its body geometry.<\/p>\r\n\r\n\r\n\r\n<p><strong>A pressure take-off in a pipe-threaded line.<\/strong> The most common use of a tapped tee is to gain a gauge port, a test point or a drain in an existing NPT line. The two run ports continue the line, the branch takes the instrument or the drain, and no separate manifold is needed.<\/p>\r\n\r\n\r\n\r\n<p><strong>Parallel branches on mobile machinery.<\/strong> In engine bays, power packs and skid units, a tapped tee splits a line to two functions at one point, and three male hose tails or nipples screw straight into the body.<\/p>\r\n\r\n\r\n\r\n<p><strong>Repair and replacement.<\/strong> Maintenance crews keep the common sizes on the shelf as junction stock, because a damaged pipe thread on a line can often be recovered by coupling through a tapped tee rather than replacing the whole run. The printed size range makes the match straightforward.<\/p>\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 for this series is organised by standard and sealing method, never by brand. Two thread adapter types interchange only if the thread form, the nominal size, the pitch, the gender, the number of ports and the outlet direction all match.<\/p>\r\n\r\n\r\n\r\n<p>A GN-PK adapter is a female tee under ANSI\/ASME B1.20.1, with a tapped thread at both ends of the run and at the branch. It is not the same part as the straight female adapter of the same thread family, because the straight version has two ports and does not split a line. It is not interchangeable with a JIC part, which seals on a 37\u00b0 or 74\u00b0 seat under SAE J514,, nor with a BSPT part, which is a 55\u00b0 taper thread under ISO 7-1.<\/p>\r\n\r\n\r\n\r\n<p>To identify the correct replacement, measure three things.<\/p>\r\n\r\n\r\n\r\n<ol class=\"wp-block-list\">\r\n<li><strong>Thread.<\/strong> Measure the outside diameter and pitch of each mating male thread, and confirm that all three ports of the replacement are the same nominal size and pitch.<\/li>\r\n\r\n\r\n\r\n<li><strong>Thread form.<\/strong> Confirm that each port is a 60\u00b0 NPT taper and not a 55\u00b0 BSPT taper or a straight thread.<\/li>\r\n\r\n\r\n\r\n<li><strong>Port arrangement.<\/strong> Confirm which two ports form the run and which port leaves at 90\u00b0, and record A, B, C and S1 so the replacement fits the same envelope. An elbow and a straight coupling are not substitutes for a tee.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<p>Where the mating port standard is not NPT, a cross standard adapter of the same size is the correct part rather than a forced thread. Record the measurements with the part number so HENGHUA can match a printed size code.<\/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 order, give the following information:<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Series code: <code>GN-PK<\/code>.<\/li>\r\n\r\n\r\n\r\n<li>Full part number, for example GN-08PK, taken from table 2.5.<\/li>\r\n\r\n\r\n\r\n<li>The tapped thread size required at all three ports, read from the E, F and G columns.<\/li>\r\n\r\n\r\n\r\n<li>The required branch direction, so the tee is clocked correctly at assembly.<\/li>\r\n\r\n\r\n\r\n<li>Sealant or dryseal thread requirement, if the joint is specified as NPTF.<\/li>\r\n\r\n\r\n\r\n<li>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<li>Quantity, destination and the packing format required.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>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 sizes and the quantity. Sample orders and first-article parts are available for OEM programmes, including drawing-based manufacture of specials.<\/p>\r\n\r\n\r\n\r\n<p>Lead time is confirmed per order and depends on size, material, plating and quantity. As a hydraulic adapter manufacturer and supplier, HENGHUA can quote this NPT adapter, the matching sealant recommendation and the packing format as one supply.<\/p>\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>What is a GN-PK adapter used for?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>A GN-PK adapter is a female tee with an internal NPT taper thread at all three ports: E on the left of the run, G on the right of the run and F on the branch. It joins three male pipe threads at one junction and splits or combines flow, and it is used where every mating connection in the circuit is a male NPT thread. There is no male end, no cone and no O-ring on the part.<\/p>\r\n\r\n\r\n\r\n<p><strong>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<p>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. This series is in neither family: it is a taper pipe thread that seals on the thread flanks.<\/p>\r\n\r\n\r\n\r\n<p><strong>Can NPT and BSPT be interchanged?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>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 form, angle and pitch differ, so the two will not seal even when a few threads start by hand. Use the thread the port is machined to, and order a cross standard adapter when the two sides differ.<\/p>\r\n\r\n\r\n\r\n<p><strong>How do I identify the correct GN-PK size?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>Measure the outside diameter and pitch of all three mating male threads, then read across the E, F and G columns of table 2.5. When all three match a printed row, that row is the correct part number. Confirm the thread form as well, because a straight thread with an O-ring groove looks similar at a glance but belongs to a different family.<\/p>\r\n\r\n\r\n\r\n<p><strong>Does a tapped NPT port need a sealant?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>Yes. A tapped taper thread of this type seals on the thread flanks, not on a seat or an O-ring, so the joint needs a sealant applied to the mating male thread, or an NPTF dryseal thread pair per SAE J476. Apply a sealant compatible with the fluid and the system temperature, and leave the first thread clean so no tape fragment enters the circuit.<\/p>\r\n\r\n\r\n\r\n<p><strong>What seal material should I select for my fluid and temperature?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>This part contains no elastomer, so the material decision is the sealant rather than an O-ring. Select a sealant compatible with the fluid and the system temperature, and apply it to all three mating male threads. If the same circuit uses elastomer-sealed components, the published ranges are approximately -30\u00b0C to +100\u00b0C for NBR, -20\u00b0C to +200\u00b0C for FKM (Viton-type) and -40\u00b0C to +120\u00b0C for EPDM.<\/p>\r\n\r\n\r\n\r\n<p><strong>How is the working pressure of this adapter determined?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>Working pressure is not fixed by the series code. It is governed by the thread size, the wall thickness of the tee body, the sealing method and the material selected, and it is limited by the three mating male threads. 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<p><strong>What is the minimum order quantity and can I get samples?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>Minimum order quantity depends on the size code, the material and the plating, so it is confirmed with the quotation rather than published as one series figure. Samples and validation parts are available for OEM and distributor evaluation, including specials made to a drawing.<\/p>\r\n\r\n\r\n\r\n<p><strong>Send your requirement to HENGHUA<\/strong><\/p>\r\n\r\n\r\n\r\n<p>Send the part number, all three tapped thread sizes, the branch direction, the sealant or dryseal requirement, the material and plating, and the quantity. HENGHUA confirms the match to the printed table, the sealant options and the delivery schedule, and quotes the GN-PK adapter that fits your circuit.<\/p>\r\n\r\n\r\n\r\n<p>Related series in the same family: <a href=\"https:\/\/www.henghuahose.com\/ar\/product\/npt-female-adapter-7n\/\" target=\"_blank\" rel=\"noopener\">the 7N adapter (straight)<\/a> and <a href=\"https:\/\/www.henghuahose.com\/ar\/product\/90-degree-elbow-npt-female-adapter-7n9-pk\/\" target=\"_blank\" rel=\"noopener\">the 7N9-PK adapter (90\u00b0 elbow)<\/a>.
