1/8英寸 x 27英寸
黄油嘴
1/8″ x 27 PTF (also referred to as NPT, ANPT, American Pipe, Briggs) have a 60° thread form and a 1:16 taper. The full definition is described in SAE J476. There is provision in SAE J534 for extra truncation on the crests of the threads.
The reference 1/8″ does not refer to the diameter of the thread. It is an old reference to the pipe size onto which the thread would be used. The nominal diameter of these threads is roughly 0.4” (approx. 10mm).
The self forming version of this thread has a 90° thread form and a 10° diametral taper.
