Anvil 0310544804 trap reducing coupling malleable iron Class 300 Schedule 80 2 in 1 1/4 in NPT 500 psi 150 F

Malleable Iron Reducing Coupling

This Anvil 0310544804 coupling joins a 2-inch female NPT pipe to a 1 1/4-inch female NPT pipe in Schedule 80 systems. It is built from malleable iron rated for Class 300 service. The fitting suits plumbing and industrial pipework that requires a durable, threaded transition between different diameters. Installers use it where a secure, leak-resistant reduction is needed.

Class 300 Schedule 80 pressure limits

The coupling handles a maximum operating pressure of 500 psi at temperatures up to 150 degrees Fahrenheit. These ratings apply only when the fitting is installed on compatible Schedule 80 pipe with properly sealed NPT threads. Exceeding either the pressure or temperature limit can compromise the joint integrity. The Class 300 designation defines the pressure-temperature envelope for this malleable iron grade.

Replaces worn or mismatched threaded reducers

Use this coupling to replace a damaged reducer or to correct a pipe size mismatch in an existing Schedule 80 NPT system. The jump is worth it when the current fitting leaks, shows corrosion, or cannot meet the 500 psi at 150 degrees F requirement. It is not suited for systems that demand a different thread standard, a higher pressure class, or a non-threaded connection method.
