What size thread we talkin on this plug, and is it a standard pipe thread or something proprietary?

Question by: Troy S on May 29, 2025, 3:17 PM

Standard NPT all the way. It's a 1-11-1/2 Male NPT thread, which is the common tapered pipe thread you'll find on most industrial pipe fittings in that size range. Nothing proprietary about it, so it should match up with any female NPT port cut to that spec.
