1/2 NPT Thread Ring Gauge National Pipe Thread Gage

        NPT part threads have a tapered internal thread that assembles with a tapered external thread. Per the ASME standard,NPT threads are intended to be made wrench tight and a sealant should be applied in pressure tight joint applications. Gaging of NPT threads is quite easy and differs from straight threads in that only one gage, an L1 plug or L1 ring is used to determine acceptability
