The MUELLER STREAMLINE w 03034cb is a 3/4-inch copper 45-degree elbow fitting designed for sweat (female soldered) connections on both ends. Manufactured to ASME B16.22 standards, this CXC fitting is part of the KLEENFIT line, which undergoes bright polishing and thorough degreasing to meet cleanliness requirements in demanding environments. It handles a wide temperature range of 350 to 550 degrees F, making it suitable for a broad range of piping applications. Licensed plumbers and pipefitters install this fitting using standard copper soldering techniques.
This elbow is appropriate for both residential and industrial piping systems. Its KLEENFIT processing makes it a strong choice for applications where cleanliness is critical, including medical facilities, food processing plants, clean room environments, and research laboratories. It also performs reliably in standard residential plumbing and hydronic systems where a 45-degree change of direction is needed on 3/4-inch copper line.
Designed as an OEM-style replacement and new-installation fitting for 3/4-inch copper piping systems using female soldered (sweat) end connections in residential and industrial applications.
Installation should be performed by a licensed plumber following applicable local codes and IPC guidelines. Shut off and depressurize the water or fluid system and drain the line before soldering. Clean all mating pipe ends and fitting cups thoroughly with emery cloth and flux before applying heat. Avoid overheating the fitting during the soldering process, as excessive heat can damage the copper and compromise joint integrity.
