Product Questions & Answers

got a manifold with a 1/2-14 NPT port i aint using. is this the right plug for that

Question by: Kirk D on Feb 18, 2026, 8:13 AM

For sealing off an unused 1/2-14 male NPT port, this countersunk hex plug is a match. It is made for plugging ports in hydraulic manifolds, valve bodies, and other industrial fluid systems, and the stainless body is meant for spots where corrosion resistance matters.

What size hex wrench do I need for this plug? Don't wanna strip it out.

You'll need a 3/8" hex key.
