2-1/2" FNPT Galvanized Pipe Cap

This Anvil pipe cap is a Class 150 fitting made from galvanized malleable iron to ASTM A197. It carries FM Approved and UL Listed marks and meets ASME B16.3. The cap seals a 2-1/2 inch female NPT thread on pipe or equipment.

Suits water, oil, gas and saturated steam lines

The fitting handles 300 psi at 150 degrees F WOG and 150 psi saturated steam at 350 degrees F across a -20 to 350 degrees F range. It is not for systems that exceed these pressure or temperature limits, nor for connections requiring a different thread standard or fitting class.

2-1/2 inch FNPT thread size

The single specification that decides fit is the 2-1/2 inch FNPT connection. Verify the mating pipe or component uses the same nominal size and thread type before ordering.

Questions about this item

Will the 2-1/2 inch FNPT threads on this galvanized cap mate with my existing Class 150 malleable iron piping?

Yes, the cap follows ASME B 16.3 dimensions for Class 150 fittings, so the FNPT threads will engage standard 2-1/2 inch malleable iron pipe of the same class.

How can I verify the cap is sealing correctly once installed?

Pressurise the system up to 300 psi at 150 °F WOG or 150 psi saturated steam at 350 °F; no leakage at the threads confirms a proper seal.

Does the box include thread sealant or a gasket, or must I buy them separately?

The cap is supplied as a single galvanized malleable iron fitting; thread sealant or PTFE tape must be purchased separately.
