  • 1/2 in FNPT fits standard pipe threads

  • No pre-applied sealant allows custom thread sealing

1/2 in FNPT Malleable Iron Cap

This 1/2 inch nominal pipe size cap features female NPT threads and a Class 150 pressure rating. It is manufactured from malleable iron for durability in industrial plumbing installations. The fitting operates across a temperature range of -20 degrees to 366 degrees Fahrenheit. It is supplied without pre-applied thread sealant or an included seal.

Suits Low-Pressure Iron Piping Systems

This cap suits installers closing a 1/2 inch female NPT connection on Class 150 malleable iron pipework. It is not for systems requiring a higher pressure class or a different thread standard. Buyers who need a cap with integral sealant or a different material should look at alternative fittings. The product carries a California Proposition 65 warning for cancer and reproductive harm.

Class 150 Pressure Rating Decides Fit

The single specification that decides whether this is the right part is the Class 150 pressure rating. Only piping systems designed for this class should use the cap. Using it on pipework rated for a different class risks leaks or failure. Verify the system pressure class before installation.

Questions about this item

What size female NPT fitting do I need to screw this 1/2 inch cap onto?

This cap has a 1/2 inch female NPT thread, so it threads directly onto a matching 1/2 inch male NPT pipe or nipple.

Will the malleable iron and Class 150 rating handle the same pressure and temperature range as my existing black iron pipe?

Yes, the malleable iron construction and Class 150 rating are standard for black iron piping systems up to 366 degrees F.

How can I confirm the seal is holding after I install the cap on the line?

Pressurise the system and check the joint for leaks; the cap contains no pre-applied sealant, so you must apply thread tape or pipe dope during assembly.
