Anvil 5 in Malleable Iron Cap

This Anvil cap closes a 5 in nominal pipe size line. It is made from galvanized malleable iron to A197 standard and uses threaded connections. The fitting suits Schedule 40 and Schedule 80 pipe. It is supplied new without pre-applied sealant.

Installers needing a 5 in threaded closure

Plumbers closing a 5 in threaded steel or iron pipe run will use this cap. It handles 300 psi at 150 Degrees F and 150 psi saturated steam at 350 Degrees F. Systems requiring a socket-weld, flanged or grooved end closure cannot use this thread-only fitting.

300 psi pressure rating at 150 Degrees F

The 300 psi maximum operating pressure at 150 Degrees F is the primary limit for water, oil or air service. Steam service drops to 150 psi at 350 Degrees F. Select this cap only when your system design stays within these pressure and temperature boundaries.

Questions about this item

Do I need Schedule 40 or Schedule 80 pipe for this 5 in threaded cap?

The cap fits both Schedule 40 and Schedule 80 pipe because its threads match the same nominal pipe size standard for either schedule.

Will this malleable iron cap handle the same 300 psi @ 150 °F rating as my existing Schedule 40 fittings?

Yes, the cap is rated 300 psi at 150 °F and 150 psi at 350 °F, matching typical Schedule 40 and 80 pressure classes in that temperature range.

How can I confirm the cap is sealing properly after I thread it onto the pipe?

Pressurise the system up to the 300 psi @ 150 °F rating and check the joint for leaks; the solid plug construction has no internal seal to fail.
