Mueller Industries MUE-A02980NL Companion Flange 2 in

Product Description

The MUELLER INDUSTRIES MUE-A02980NL is a Class 150 companion flange fitting designed for copper solder-joint plumbing systems. Manufactured from lead-free cast brass alloy, this fitting connects a 2-inch cup (female solder) end to a 2-inch flange end, making it a direct interface point between copper tubing runs and flanged equipment or valves. It meets a full suite of ASME dimensional and pressure standards, confirming dimensional accuracy and material integrity. Licensed plumbers and pipefitters install this fitting in above-ground potable water supply and pressurized distribution systems where a reliable, code-compliant copper-to-flange transition is required.

This fitting is suited for residential and light commercial above-ground potable water supply systems. It is used wherever a copper solder-joint line must terminate at a flanged connection, such as at pump inlets, valve flanges, or equipment tie-ins. The cup end accepts standard 2-inch copper tubing for conventional sweat soldering, while the companion flange face mates to a corresponding Class 150 flange. Installers working on pressurized domestic water systems will find this fitting appropriate for both new construction and retrofit applications.

Key Features

• Lead-free cast brass alloy construction meets potable water material requirements
• Class 150 companion flange configuration for pairing with standard Class 150 flanged components
• 2-inch cup (C) end accepts copper tubing for sweat solder connection
• 2-inch flange (FLNG) end for bolted flange assembly
• Compliant with ASME B16.15, B16.18, B16.22, B16.24, B16.50, and B1.20.1
• Rated for above-ground potable water supply and pressurized systems per CDA pressure-temperature guidelines

Compatibility

Designed as an OEM-style solder-joint copper fitting for above-ground potable water supply and pressurized piping systems using standard 2-inch copper tubing with Class 150 flanged terminations.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code and applicable local codes. Shut off and depressurize the water supply system completely before cutting into any existing line. The cup end requires standard sweat soldering with lead-free solder; ensure all surfaces are clean, deburred, and properly fluxed before applying heat. Torque fasteners on the flange face evenly in a cross pattern to the flange manufacturer's specification, and verify all joints for leaks before returning the system to service.
