got a port i need to cap off, is this the kind of plug that’ll do it if the threads are 1-1/2-11-1/2 npt?

Question by: Randy H on Dec 25, 2025, 9:58 AM

For capping off a 1-1/2-11-1/2 male NPT connection, this is a steel countersunk hex plug with that exact male NPT thread, so it’s meant to thread in securely and help minimize leaks when installed properly.

what tool do i need to pull this plug out if i gotta get in there for maintenance?

Question by: Cody M on Sep 17, 2025, 6:22 PM

A standard Allen wrench handles it. The countersunk hex design means you're not dealing with a traditional hex head on the outside, so a hex key or Allen socket in the right size is what you want. Makes it pretty straightforward to swap out without a lot of fuss.

What size Allen wrench do I need for this plug?

Question by: Sherry M on Aug 4, 2025, 6:43 PM

This plug uses a countersunk hex design, so standard Allen tools should work for installation and removal.
