Brass Plug for Pipe Closure

The 1-1/2 inch male NPT brass plug seals the end of a pipe or fitting in plumbing and pneumatic systems. Its square head allows installation with a standard wrench. The fitting is rated for 200 psi maximum operating pressure and a temperature range of -20 to 400 degrees F. Class 125 construction suits general-purpose water, air and oil lines.

Suitable Uses and Limitations

This plug suits installers closing a 1-1/2 inch NPT female port on brass, steel or iron pipe where a square-head design is preferred. It is not for systems exceeding 200 psi or 400 degrees F. Buyers needing a hex head, a different thread standard or a plug with an integrated seal should look at other fittings. The item contains chemicals listed under California Proposition 65.

1-1/2 Inch Male NPT Thread

The single deciding specification is the 1-1/2 inch male NPT thread size. It only mates with a matching female NPT opening of the same nominal diameter. Verify the thread standard and nominal size on the receiving port before purchase to ensure a proper seal.

Questions about this item

Should I choose the 1-1/2" size or a different nominal pipe size?

Select the 1-1/2" nominal pipe size only when your piping system matches that exact dimension; other sizes will not seal on these threads.

What does the 200 psi rating mean once the plug is installed?

It indicates the maximum operating pressure the brass plug can withstand at temperatures between -20 and 400 degrees Fahrenheit.

How does the Male NPT thread standard affect sealing in practice?

Male NPT threads create a tapered seal that tightens as you torque the plug, limiting leakage up to the 200 psi class 125 rating.
