The MUELLER STREAMLINE COTRED343412 is a copper reducing tee fitting manufactured from ASTM B75 Alloy C12200 copper. It measures 3/4 x 3/4 x 1/2 inches and connects a continuous pipeline while branching out in a separate direction. The fitting uses solder cup connections for a reliable, leak-resistant joint. It is lead free and dezincification resistant, making it suitable for potable water and medical gas applications. Third-party certified to NSF/ANSI 61 Annex G, it meets strict material and performance requirements for systems carrying drinking water. Licensed plumbers and pipefitters install this fitting in residential and commercial applications.
This reducing tee is suited for both residential and commercial plumbing systems where a 3/4-inch main line requires a 1/2-inch branch takeoff. It is listed for use in healthcare facility gas and vacuum systems under NFPA 99 and complies with the Compressed Gas Association Pamphlet G4.1 for medical gas installations. Its compliance with ASME B16.22, MSS SP-104, and MSS SP-109 makes it appropriate for a broad range of pressure piping applications in mechanical and plumbing systems.
Designed as an OEM-style replacement or new-installation fitting for copper sweat-connection plumbing and gas piping systems requiring a 3/4 x 3/4 x 1/2 inch reducing tee configuration.
Installation should be performed by a licensed plumber in accordance with the applicable local plumbing code, IPC, or IFGC requirements. Shut off and drain the water or gas supply completely before cutting into an existing line. Clean pipe ends and fitting cups thoroughly with flux and use appropriate lead-free solder when joining. For medical gas applications, follow NFPA 99 procedures and use only qualified personnel certified for medical gas piping work.
