Mueller Industries MUE-W02052NL Companion Flange 5 in

Product Description

The MUELLER INDUSTRIES MUE-W02052NL is a two-piece wrot copper companion flange fitting designed to connect copper piping systems to flanged connections in commercial and residential plumbing installations. Rated to 125/150 lb. flange service, this fitting features a cup-end copper sleeve that accepts soldering or brazing using the same techniques applied to standard wrot copper fittings. The EPDM insulator delivers full electrolysis protection both above and below grade, while the epoxy-coated backing ring accommodates alignment adjustments and guards against deflection and corrosion. At 19.5 pounds, the assembly is built for demanding service conditions. Licensed plumbers and pipefitters are the primary installers of this fitting.

This companion flange is suited for 5-inch copper piping systems in applications where a copper-to-flange transition is required. Typical installations include mechanical rooms, water distribution mains, and industrial process piping where flanged connections are specified. The two-piece construction simplifies field assembly and provides a finished, professional appearance. The fitting meets NSF 61G requirements, making it appropriate for potable water service, and conforms to ASME B16.22 and ASME B16.50 dimensional standards for wrought copper and copper alloy fittings.

Compatibility

Designed as an OEM-style wrot copper companion flange for 5-inch copper piping systems requiring a solder cup to flanged transition in potable water or general plumbing service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing codes, including IPC requirements for flanged connections. Shut off and depressurize the water system completely before cutting into the line or assembling the fitting. Clean and flux all mating copper surfaces before soldering or brazing per standard wrot copper fitting procedures. Do not over-tighten the backing ring hardware, and verify flange bolt-hole alignment before finalizing the joint.
