Reducing Coupling 1-1/2" x 2

The Zoro Select 222138 is a straight cast iron reducing coupling designed to join a 1-1/2 inch pipe to a 2 inch pipe. Both ends use female socket connections for a secure fit. The grey cast iron construction provides durability for plumbing installations. This new component suits residential and commercial pipework modifications.

Class 20 Cast Iron Rating

The coupling meets Class 20 specifications with a maximum operating pressure of 0 psi, indicating it is intended for non-pressure drainage or vent systems rather than pressurised supply lines. Bitumen coating adds corrosion resistance to the grey cast iron body. Verify that your system operates within these limits before specifying this part.

Simple Socket Installation

Installation requires inserting each pipe end into the corresponding female socket; no threading or specialised tools are needed. The differing socket depths of 2 13/32 in and 1 61/64 in mean pipes must be cut to the correct insertion length. Ensure the system is non-pressurised, as this fitting is not rated for pressure applications.
