The NIBCO M055450 is a 1/2-inch CPVC 90-degree elbow fitting designed for hot and cold water distribution systems in residential and light commercial plumbing applications. Constructed from chlorinated polyvinyl chloride (CPVC), this fitting handles maximum working temperatures up to 180 degrees F, making it suitable for domestic hot water lines where standard PVC would be inadequate. The slip-by-slip end connections accept standard CPVC solvent cement for a secure, leak-free joint. At 0.025 pounds, the fitting is lightweight and easy to handle during installation in tight spaces. Licensed plumbers and pipefitters are the primary installers of this component.
This elbow is used wherever a 90-degree change of direction is needed in a 1/2-inch CPVC piping run. Typical applications include residential hot and cold water supply lines, hydronic distribution in smaller systems, and commercial plumbing where CPVC is the specified pipe material. The fitting is compliant with ASTM and NSF/ANSI standards, including NSF U.P. certification, making it appropriate for potable water service. It is sold individually but must be ordered in multiples of five.
Designed as an OEM-style replacement or new-construction fitting for 1/2-inch CPVC piping systems using solvent-cement slip connections.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off and depressurize the water supply before cutting into any existing line. Use only CPVC-rated solvent cement and primer when joining slip connections, and allow full cure time before pressurizing the system. Do not use this fitting with PVC solvent cement or on systems that exceed the rated temperature or pressure limits of CPVC pipe.
