45° Cast Iron Elbow 1-1/2" FNPT

This Anvil 0300028800 is a 45-degree elbow designed for drainage and trap assemblies. It connects two sections of 1-1/2 inch Schedule 40 pipe using female National Pipe Thread ends. The cast iron construction meets Class 125 specifications for standard plumbing installations.

Replaces worn or damaged threaded elbows

Swapping this fitting into an existing line restores the intended flow angle without re-piping the whole run. The jump is worth it when the old elbow leaks at the threads, cracks from stress, or no longer aligns after settlement. A direct thread-to-thread exchange keeps downtime short.

Handles 175 psi at 150 °F

The Class 125 rating gives comfortable headroom for typical residential and light commercial drain pressures. It runs out when system pressure exceeds 175 psi or fluid temperature surpasses 150 degrees Fahrenheit, conditions that call for a higher-class fitting.
