The Introduction of SAE Adapter NPTF and SAE JIC 37° Female Thread Adapter

1. SAE adapter NPTF

It is one kind of NPTF, the domestic taper pipe thread that used for transporting fuel, also used for both the male thread end fittings and female thread end fittings.

NPTF male threads can match with NPTF, NPSF or NPSM female threads. SAE adapter NPTF is similar to SAE adapter BSP/BSPT but they are not interchangeable. Most threads have different pitches while the angle of thread tooth type is 60 °, but the tooth type angle of BSPT thread is 55 °.

2.SAE JIC 37° female thread adapter

Society of Automotive Engineers (SAE) make the provision that 37 ° cone angle or cone seat can be used for high-pressure hydraulic pipe lines. Such fittings are usually referred to JIC fittings. JIC male thread is ruled so that only matched with the JIC female thread, because both are straight threads, and have 37 degree cone seats. Sealing is formed in a 37 ° cone seat surface, some threads are the same to SAE adapter NPTF 45 °, it should carefully measure the angle to make that distinction.
