A straight female-threaded coupling in SS304 stainless steel for joining two 3\/4\u2033 pipes end to end. Both ends carry 3\/4\u2033 PT \/ BSPT taper threads, so the joint pulls up tight without extra sealing parts beyond the usual thread sealant.<\/p>\n

Two body lengths are stocked \u2014 3\/4\u2033\u00d720L<\/b> (short) and 3\/4\u2033\u00d730L<\/b> (extended reach) \u2014 so you can pick the body that suits the run. Building a threaded line?

What size is this coupling?<\/b> 3\/4\u2033 female threads on both ends, in two body lengths \u2014 20L for tight spots and 30L for extended reach.<\/p>\n

Is it only available in SS304?<\/b> 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.<\/p>\n

20L or 30L \u2014 which should I pick?<\/b> 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.<\/p>\n

What is the difference between a coupling and a union?<\/b> A coupling is a one-piece sleeve \u2014 to remove it you unscrew the pipe. A \u0627\u0644\u0627\u062a\u062d\u0627\u062f<\/a> splits into 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.<\/p>\n
