\u88fd\u54c1\u8aac\u660e<\/h2>\n

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. The body is sand cast in our own plant in Taiwan and rated Class 150.<\/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. It is a full coupling: the same 3\/4\u2033 thread at both ends, one piece, no moving parts.<\/p>\n

    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 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.<\/p>\n
