Minimum = 0.033P for all pitches. See table for maximum. When using L1 gauges to check threads, the thread is within permissible tolerance if the ring gauge face, or plug gauge notch, is +/- 1 turn from being flush with the end of the thread. Example designation: 3/8 - 18 NPT. where: 3/8 = nominal pipe size. 18 = number of threads per inch.

Metric 60° Cone. DIN 7631. The male connector has a 60° recessed cone and a straight thread; the has a straight thread as well, and a globeseal seat. The seal forms between the recessed cone on the male and the tapered nose of the female. The threads of both halves mesh to form a strong mechanical bond.

Male Thread Thread Step 2 - Tapered Threads v. Parallel Threads Next, determine if the thread is tapered or parallel. Tapered threads become narrower as they extend outward while parallel threads remain the same diameter. Sometimes this characteristic can be determined through visual inspection, but if not a caliper can come in handy.

The pitch is the distance from the crest of one thread to the next in pitch can be displayed or omitted after thread size 3/4” – 14 NPT.
