Nibco B071150 Cast Copper 90 Elbow 2 in C X M

Product Description

The NIBCO B071150 is a cast copper 90 degree elbow fitting designed for use in pressure piping systems. It features a C x M (solder cup by male) end connection, allowing it to connect copper tubing on the socket end to a male threaded fitting on the opposite end. At 2 inches fitting size, this elbow is used to change flow direction by 90 degrees in supply lines. It is suited for licensed plumbers working on residential and light commercial water distribution, heating, and cooling piping systems where copper is the specified material.

This fitting is appropriate for pressure applications in potable water supply, hydronic heating, and general plumbing systems where a directional change is required. The C x M configuration is commonly used when transitioning from copper tubing to a threaded male connection point such as a valve, fixture, or equipment port. It is installed by trained plumbers and pipefitters in both new construction and retrofit scenarios.

Key Features

• Cast copper construction for durability and reliable pressure performance
• 90 degree elbow geometry for directional change in piping runs
• C x M end connection — solder cup inlet, male threaded outlet
• 2 inch fitting size suitable for main distribution and large-branch lines
• Pressure fitting rating appropriate for standard plumbing supply applications

Compatibility

Designed as an OEM-style replacement and standard-use fitting for copper pressure piping systems requiring a 2 inch, C x M, 90 degree elbow connection.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing codes. Shut off the water supply and depressurize the line before cutting, fitting, and soldering. Use appropriate flux and lead-free solder for potable water applications. Inspect the solder joint for full penetration and allow adequate cooling before restoring system pressure.
