3/4 in NPT malleable iron cap
This Anvil 0318901329 cap is a Class 3000 malleable iron fitting with female NPT threads. It suits piping systems that require a solid plug construction at 3/4 in nominal pipe size. The component is intended for drain, waste or vent installations where a threaded closure is specified.
Pressure and temperature ratings
The cap withstands 2,000 psi at 150 degrees F maximum operating pressure and 300 psi at 550 degrees F maximum steam pressure. Service temperature spans from -20 degrees to 550 degrees F. These ratings cover normal hydraulic and low-pressure steam service without additional derating.
No sealant or gasket included
The fitting ships without pre-applied thread sealant and without an included seal. Installers must supply compatible pipe thread compound or tape to achieve a leak-tight joint. The solid plug design means no internal moving parts require maintenance.

Questions about this item
How do I install the 3/4 in NPT female threads on this malleable iron cap without cross-threading?
Start the cap by hand until the NPT threads engage smoothly for several turns, then tighten with a wrench; the taper seals as it seats, so forcing it early causes leaks.
Will the pre-applied thread sealant on this Class 3000 cap need replacement during service?
The cap ships without pre-applied sealant or an included seal, so you apply your own thread compound or tape at install and refresh it whenever the joint is broken for maintenance.
At what temperature does the 2,000 psi pressure rating of this 3/4 in malleable iron cap begin to drop?
The 2,000 psi rating holds at 150 degrees F; above that temperature the allowable pressure decreases toward the 300 psi steam limit at 550 degrees F.
