Anvil 1/8" FNPT Pipe Cap

The Anvil 0318900008 is a Class 150 malleable iron pipe cap with a 1/8 inch female NPT thread. It is designed to close the end of a pipe in plumbing, compressed air or low-pressure steam systems.

Suits installers closing a 1/8" female-threaded port

This cap fits builders and maintenance crews who need a solid malleable iron plug rated for 300 psi at 150 °F and 150 psi saturated steam at 350 °F. It is not for systems that require a pre-applied thread sealant, an included gasket, or a different nominal pipe size or pressure class.

1/8" Female NPT thread

The single specification that decides fit is the 1/8 inch female NPT thread. Match this thread size and type to the pipe or fitting you are capping; any other thread standard or diameter will not seal correctly.

Questions about this item

What does the Class 150 rating mean for this 1/8" cap once installed?

Class 150 means the cap is rated for 300 psi at 150 °F and 150 psi at 350 °F steam, so it will hold those pressures at the stated temperatures.

How does the Female NPT thread affect sealing on this 1/8" pipe cap?

The Female NPT taper threads seal by thread interference; no seal or pre-applied sealant is included, so you apply pipe tape or compound during installation.

What are the physical dimensions and material of this 1/8" cap for fitting?

The cap is made of malleable iron with a solid plug construction, nominal 1/8 inch pipe size, and operates from -20 °F to 350 °F.
