\u7522\u54c1\u8aaa\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

It is a full coupling: the same 3\/4\u2033 thread at both ends, one piece, no moving parts.<\/p>\n
