For a 2 1/2-8 NPT fitting, how many threads are present in one inch of thread length?

Explanation:
In NPT fittings, the designation after the dash is the threads per inch. So for a 2 1/2-8 NPT fitting, the 8 means there are eight threads in every inch of threaded length. The 2 1/2 is the nominal pipe size and doesn’t tell you how many threads per inch. Therefore, one inch of thread length contains eight threads. This standardized pitch helps ensure proper assembly and sealing with pipe thread fittings.
