1\/8″ x 27 PTF (also referred to as NPT, ANPT, American Pipe, Briggs) have a 60\u00b0 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. <\/strong><\/p>\n<\/div>

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\u201d (approx. 10mm).
\nThe self forming version of this thread has a 90\u00b0 thread form and a 10\u00b0 diametral taper.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>
