WebBritish Standard Pipe Taper thread (BSPT) whose diameter increases or decreases along the length of the thread. BSPT thread is used where pressure-tightness is made through the mating of two threads together. International standards require all Female thread is parallel and male thread is tapered. WebNPT stands for National Pipe Thread and is an American standard thread. It may also be reffered to as MPT , MNPT or NPT (M) for male external threads and FPT, FNPT or NPT (F) for female interal threads. A thread sealant must always be used to achieve a leak free seal (except for NPTF). WebThe L-1 basic hand tight engagement applies to NPTF threads.
