these fit standard 3/4 NPT pipe threads, right? not lookin to order something that won't thread on proper
Answer by: Customer Support on Jun 20, 2025, 6:12 AM
the P-31 is sized specifically for 3/4 NPT tapered pipe threads, so it'll seat the way you'd expect on standard NPT fittings. The tapered profile is what locks it in place without needing any sealant or tape.

got a 3/4 NPT female pipe port i want to keep clean in the shop, is this plug the right size?

For a 3/4 NPT threaded opening, the 3/4 NPT tapered protective plug is the matching size. It is meant as a protective closure for pipe threads.
