Mueller Industries MUE-W02802NL Flange 3 in C X Flange

Product Description

The MUELLER INDUSTRIES MUE-W02802NL is a two-piece, wrot copper companion flange fitting designed for 3-inch copper piping systems. It connects a cup-end (female solder) copper pipe to a flanged connection, making it suitable for both above-ground and below-ground plumbing installations. The copper sleeve allows a licensed plumber to solder or braze the joint using standard wrot copper fitting techniques. An EPDM insulator delivers 100% electrolysis protection, and an epoxy-coated backing ring adjusts for alignment while guarding against deflection and corrosion. The assembly weighs 9.30 pounds and meets NSF 61G, ASME B16.22, and ASME B16.50 standards.

This companion flange is suited for residential and commercial plumbing applications where a copper pipe must terminate at a flanged connection point. Typical installations include mechanical rooms, pump connections, and equipment hookups where the 125/150 lb. flange rating is specified. The two-piece design simplifies field assembly and produces a clean, professional finish. It is appropriate for use in both exposed and buried piping configurations where corrosion and electrolytic protection are required.

Key Features

• Two-piece wrot copper construction allows soldering or brazing using standard copper fitting techniques
• EPDM insulator provides 100% electrolysis protection for above-ground and below-ground service
• Epoxy-coated backing ring adjusts for alignment and resists deflection and corrosion
• 3-inch cup (C) inlet to 3-inch flange outlet configuration
• Meets NSF 61G for drinking water system components
• Complies with ASME B16.22 and ASME B16.50 dimensional and pressure standards

Compatibility

Designed as an OEM-style replacement or new-installation companion flange for 3-inch wrot copper piping systems rated at 125/150 lb. flange service in residential and commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the water supply and allow all pipe surfaces to cool completely before beginning work. The copper sleeve end is soldered or brazed using standard techniques appropriate for wrot copper fittings. Do not overtighten flange fasteners beyond hardware manufacturer specifications, and verify proper alignment using the adjustable backing ring before final assembly.
