    British

    British Standard Pipe fittings are among the most popular of all foreign threads in the world today.  These threads come in two versions: parallel (BSPP), and tapered (BSPT).  The thread flank angle for both tapered and parallel British threads is 55°.  Although BSP is a foreign thread, it isn’t actually metric.  This is why it comes in Imperial sizes: 1/8, 1/4, 1/2, 3/4, etc.

    British tapered threads (BSPT)

    BSP parallel (BSPP) threads commonly seal via a 30° chamfer on the male thread to a 30° cone seat inside the female thread (swivel only).  If it is a port application, an O-ring and washer, Elastomeric seal or a bonded washer are needed to achieve a proper seal for parallel threads.  For tapered BSP threads (BSPT), a seal is accomplished via thread wedging with additional support from thread dope or tape.  As previously mentioned, it is possible for a male BSPT (tapered) to thread into a female BSPP (parallel), so long as the female thread is fixed and not swivel (this is because the recessed cone seat could interfere with clearance).

    Japanese (JIS) tapered and parallel fittings

    Japanese (JIS) tapered and parallel fittings are identical to British standard pipe threads, and are therefore considered to be in the ‘British Fitting’ group.  The only difference is that parallel JIS threads have a 30° cone seat on the male end, and a 30° flared seat on the female ends.  JIS tapered threads are identical to BSPT threads.

    British tapered threads (BSPT)

    For British tapered threads (BSPT) caution should be taken as the most common tapered fitting in North America is NPT.  The easiest way to distinguish any tapered fitting type from NPT is to verify if a chamfered sealing surface exists.  If it does the fitting is most likely NPT.  If not, it is either BSPT or Metric Taper (Metric Taper is far less common).
