Anvil Malleable Iron Reducing Coupling

The Anvil 311091201 is a straight reducing coupling made from malleable iron with a galvanised finish. It connects a 3 inch NPT female threaded pipe to a 1-1/2 inch NPT female threaded pipe in plumbing and industrial piping systems.

Class 150 Pressure Rating Constraints

This fitting is rated for Class 150 service with a maximum operating pressure of 300 psi at 150 degrees F. It is designed for use with Schedule 40 pipe, limiting its application to systems that stay within these pressure and temperature boundaries.

Galvanised Construction and Threaded Installation

The galvanised malleable iron body provides corrosion resistance for water, air and oil lines. Both ends feature female NPT threads, so installation requires male-threaded pipe nipples or fittings and thread sealant to achieve a leak-free joint.
