Merit Brass XB235-20 Companion Pipe Flange Class 125

Product Description

The MERIT BRASS XB235-20 is a companion pipe flange designed for 1-1/4 inch pipe connections in plumbing and mechanical piping systems. Constructed from brass with a chrome plated finish, this Class 125 flange provides a corrosion-resistant mating surface for flanged joint assemblies. It features a 4-5/8 inch outer diameter and a 13/16 inch hub length, with four bolt holes spaced 3-1/2 inches across bolt hole centers. Licensed plumbers and pipefitters install this type of flange where a bolted, gasketed connection is required on low-pressure service lines.

This companion flange is suited for residential and light commercial plumbing installations where 1-1/4 inch flanged connections are specified. It is commonly used in water supply, drain, and low-pressure service piping where a removable flanged joint is required for maintenance access or equipment connections. The chrome plated finish makes it appropriate for exposed or semi-exposed installations where appearance matters alongside function.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements.

Verify bolt hole alignment before drawing fasteners to even torque in a cross pattern.
