2-1/2 Inch FNPT Pipe Cap
The Zoro Select 4316000266 cap seals a 2-1/2 inch female NPT pipe end. It is made from malleable iron with a 300 class pressure rating. The black finish provides corrosion resistance for plumbing installations. This fitting suits industrial and commercial pipe systems.
Thread Compatibility and Pressure Rating
Verify that the mating pipe has a matching 2-1/2 inch male NPT thread before ordering. Confirm the system operating pressure does not exceed the 300 class rating of this cap. Ensure the malleable iron material is compatible with the fluid being conveyed. Check that the black coating meets project specifications.
Thermal and Pressure Performance
Malleable iron construction handles typical plumbing temperature ranges without deformation. The solid cap design creates a reliable seal under rated pressure conditions. No moving parts mean silent operation during pressure changes. The fitting adds minimal flow restriction when installed in the closed position.

Questions about this item
What is included with the Zoro Select 4316000266 Cap and do I need to buy thread sealant separately?
The box contains the malleable iron cap with 2-1/2" FNPT threads; thread sealant or tape is not included and must be purchased separately.
How do I decide between the 300 class rating and other pressure classes for my piping system?
The 300 class rating indicates the pressure-temperature capability of this malleable iron fitting; select the class that matches or exceeds your system design pressure and temperature requirements.
What does the 300 class rating mean once the cap is installed on a 2-1/2" pipe in a real plumbing system?
It means the cap is designed to withstand the pressure and temperature limits defined for 300 class malleable iron fittings when properly threaded onto a 2-1/2" pipe with appropriate sealant.
