Anvil 2 1/2" Class 150 Coupling

This Anvil malleable iron coupling joins two 2 1/2 inch NPT threaded pipes in a straight line. The galvanized Class 150 fitting suits water, air or oil lines in commercial and industrial plumbing. It is built for new installations or repairs where a rigid, leak-tight joint is required.

Class 150 pressure and temperature envelope

The coupling is rated for 300 psi at 150 degrees F maximum operating pressure. This limit defines the safe envelope for Schedule 40 piping systems. Service above this pressure or temperature requires a higher-class fitting not supplied here.

Schedule 40 capacity and headroom

The straight coupling matches Schedule 40 wall thickness for 2 1/2 inch nominal pipe, giving full bore flow with no restriction. It handles standard hydraulic and pneumatic loads within the Class 150 envelope. Systems needing higher pressure ratings or larger diameters must use heavier fittings.

Questions about this item

How do I choose the right size for this coupling?

The coupling is a 2 1/2 inch NPT straight fitting in Class 150 malleable iron, galvanised for Schedule 40 pipe.

What does the 300 psi rating mean in daily use?

It indicates the maximum operating pressure at 150 degrees Fahrenheit, so the joint will hold up to that pressure at that temperature.

Does the NPT threading limit the pressure I can run?

The 2 1/2 inch female NPT threads are rated to the same Class 150 limit of 300 psi at 150 degrees Fahrenheit.
