Stainless Steel Pipe Coupling — SS304, 3/4″ Female PT Both Ends

وصف المنتج

A straight female-threaded coupling in SS304 stainless steel for joining two 3/4″ pipes end to end. Both ends carry 3/4″ PT / BSPT taper threads, so the joint pulls up tight without extra sealing parts beyond the usual thread sealant. The body is sand cast in our own plant in Taiwan and rated Class 150.

Two body lengths are stocked — 3/4″×20L (short) and 3/4″×30L (extended reach) — so you can pick the body that suits the run. It is a full coupling: the same 3/4″ thread at both ends, one piece, no moving parts.

التطبيقات

• Straight-run extension and repair — joining two pipe lengths in line, or bridging a new section where a damaged one was cut out.
• أنابيب المواد الكيميائية وأنابيب العمليات — stainless lines carrying process fluids in chemical, pulp and paper and petroleum plants.
• Plant utility lines — water, compressed air and nitrogen distribution runs through the plant.
• Pump and filtration skids — well pumps, pressure tanks and filter housings where a low-profile coupling fits and a bulky iron coupler does not.
• Water treatment piping — treatment plant and filtration system lines built in stainless.

الأسئلة الشائعة

What size is this coupling? 3/4″ female threads on both ends, in two body lengths — 20L for tight spots and 30L for extended reach.

Is it only available in SS304? This coupling is stocked in SS304 stainless steel. If your job calls for a different grade or size, tell us with the inquiry and we will confirm what we can supply.

20L or 30L — which should I pick? They join pipes the same way; the 30L body simply gives you more thread engagement and reach. If the run is tight, use 20L; if you need to bridge a longer gap, use 30L.

ما هو معيار الخيوط المستخدم؟ PT / BSPT taper threads. Tell us your pipe thread standard when you request a quote and we will confirm the fit.

What is the difference between a coupling and a union? A coupling is a one-piece sleeve — to remove it you unscrew the pipe. A union splits into three parts so the line can be opened without turning the pipe. Use couplings for permanent runs and unions where you expect to service the line.
