Threads - NPTF Taper Thread Gaging
NPTF product threads. On class 1 threads the acceptability is determined by the coordinated use of L-1 and L-3 thread plug gages for internal product threads and L-1 and L-2 thread ring gages for external product threads. Crest and root truncations are generally considered adequately controlled by the tooling used to produce the product threads.
