Anvil Malleable Iron Coupling Class 150

This Anvil 0310081203 coupling is a malleable iron fitting rated Class 150 for Schedule 40 pipe. It connects two 2-inch female NPT threads in a straight line. The black finish identifies the standard coating.

Suited for low-pressure water, air or gas lines

Installers joining two female NPT ends on Schedule 40 pipe at or below the rated pressure will find this fitting matches the spec. Systems requiring a different thread standard, a larger bore or a higher pressure class need a different component.

300 psi at 150 °F maximum operating pressure

The coupling holds up to 300 psi at 150 degrees Fahrenheit. Exceeding this pressure or temperature limit risks joint failure. Verify the system design stays within this envelope before specifying the part.
