Mueller Streamline COCOUPLS212 Copper Coupling 2-1/2 in

Product Description

The MUELLER STREAMLINE COCOUPLS212 is a 2-1/2 inch wrot copper coupling less stop, designed for solder (sweat) connections on copper tube systems. Built to the C x C end configuration, this fitting includes no internal stop, which allows it to be slid freely along tubing for in-line pipe repair without cutting out additional material. It is manufactured from ASTM B75 Alloy C12200 phosphorus-deoxidized copper and meets lead-free requirements. Plumbers and pipefitters install this fitting in water distribution, medical gas, and other copper piping systems where a clean, reliable solder joint is required.

This coupling is suited for residential and commercial plumbing repairs, new construction copper piping runs, and medical gas installations. The absence of an internal stop makes it particularly useful for repair applications where the fitting must be repositioned over existing tube ends. It is third-party certified to NSF/ANSI 61 Annex G, making it acceptable for potable water service. NFPA 99 and Compressed Gas Association Pamphlet G4.1 compliance also qualifies it for health care facility gas and vacuum systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the water or gas supply before cutting into any existing line. Clean and flux all mating tube ends thoroughly before soldering; use only lead-free solder on potable water or medical gas systems. Medical gas installations must comply with NFPA 99 and are restricted to qualified personnel holding the appropriate certifications.
