Product Questions & Answers

what thread size is on this plug, is it the 1/4-18 NPT?

Question by: Floyd R on Dec 20, 2025, 12:15 PM

That's correct, it's a 1/4-18 male NPT thread. The countersunk hex head style means it sits flush or recessed when installed, which works well when clearance is tight and a standard raised plug head would get in the way.
