3-Inch Malleable Iron Cap

This Anvil cap is a solid-threaded pipe fitting made from galvanized malleable iron to A197 specification. It terminates a 3-inch nominal pipe run in residential, commercial or industrial plumbing systems. The fitting is rated for 300 psi at 150 degrees F and 150 psi saturated steam at 350 degrees F.

Thread Compatibility And Sealant

Verify that the existing pipe uses matching tapered threads for a 3-inch nominal size and that the schedule is either 40 or 80. The cap ships without pre-applied thread sealant, so installers must supply a compatible compound or tape before assembly.

Galvanized Iron Durability

The galvanized malleable iron body resists corrosion in water and steam service across a -20 to 350 degrees F range. Solid plug construction with no moving parts means the joint stays tight through thermal cycling and vibration once properly tightened.

Questions about this item

Does the Anvil 319900841 cap come with thread sealant or a gasket, or must I buy them separately?

The cap is supplied without pre-applied thread sealant and without an included seal, so PTFE tape, pipe dope or a compatible gasket must be purchased separately.

Should I choose the Schedule 40 or Schedule 80 rating for a 3-inch galvanised malleable iron cap?

The same cap is rated for both Schedule 40 and Schedule 80 pipe, so the choice depends on the pipe you are joining rather than the fitting itself.

What does the 300 psi at 150 °F rating mean when the cap is installed on a hot-water line?

At water temperatures up to 150 °F the cap can safely hold 300 psi; if the system runs hotter the allowable pressure drops, reaching 150 psi at 350 °F.
