Nibco 150COMPFLG-212 Cast Brass Flange 2.5 in 150 Class

Product Description

The NIBCO 150COMPFLG-212 is a 2.5-inch Class 150 cast brass companion flange designed to adapt a solder cup connection to a flanged pipe connection. This one-piece fitting features a solder cup end and a flat flange face, allowing a copper sweat joint to transition cleanly into a bolted flange assembly. It is manufactured in an ISO 9001 certified facility and backed by a 50-year limited warranty. Plumbers and pipefitters install this fitting in copper piping systems where a flanged connection point is required at a valve, pump, or equipment tie-in.

This fitting is suited for use in residential and commercial plumbing systems and mechanical piping applications where copper is the specified material. The Class 150 pressure rating makes it appropriate for standard water service and low-pressure fluid systems. It is a lead-free construction, meeting requirements for potable water applications. Copper's durability and low maintenance characteristics also make this fitting a practical choice for sustainable building projects where material reusability is a project consideration.

Compatibility

Designed as an OEM-style companion flange for 2.5-inch copper piping systems using Class 150 flanged connections in standard plumbing and mechanical installations.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing codes, including the IPC. Shut off and depressurize the system and allow all components to cool completely before soldering the solder cup connection. Use appropriate flux and solder rated for the service type, and ensure the flange face and mating gasket are clean and properly aligned before torquing bolts. Do not over-stress the copper tube during flange bolt tightening.
