got a 3/4-14 NPT port I need to cap off on a steel manifold block, this the right plug for that?

Question by: Jimmy T on Jul 17, 2025, 4:30 PM

For a 3/4-14 NPT port, yeah, this one fits. The thread size matches exactly, and the male NPT configuration is built for pipe-to-pipe connections on steel components like manifold blocks. The countersunk hex design means you drive it with an Allen wrench rather than a standard wrench, so keep that in mind if you're working in a tight spot.
