Nibco B070900 Cast Copper 90 Elbow 1-1/2 in C X M

Product Description

The NIBCO B070900 is a cast copper 90 degree elbow designed for pressure piping applications in residential and commercial plumbing systems. It features a C x M (sweat socket by male) end connection, allowing one end to be soldered onto copper tubing while the male threaded end connects to a female-threaded fitting or valve. Sized at 1-1/2 inches, this elbow is used to redirect flow at a right angle within a copper pipe run. Licensed plumbers and pipefitters install this fitting as part of pressure-rated supply, distribution, and hydronic systems.

This fitting is suited for new construction and retrofit plumbing projects where a 90 degree directional change is required in a 1-1/2 inch copper line. The C x M configuration is common in connections to valves, adapters, and equipment with female-threaded inlets. It is appropriate for both hot and cold water supply lines and light commercial plumbing installations where cast copper pressure fittings are specified.

Key Features

• 90 degree elbow geometry for right-angle direction changes in copper pipe runs
• C x M end connection: sweat socket on one end, male thread on the other
• Cast copper construction for pressure-rated service
• 1-1/2 inch fitting size for standard pipe sizing compatibility
• Pressure fitting style rated for supply and distribution applications

Compatibility

Designed as an OEM-style replacement and new-installation pressure fitting for 1-1/2 inch copper piping systems using sweat and male-threaded connections.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off and depressurize the water supply and drain the line before cutting or joining any fittings. The sweat socket end requires proper flux application, a clean pipe surface, and a torch for soldering; the male threaded end should be joined with appropriate thread sealant or PTFE tape. Do not overtighten the threaded connection or apply heat to a pressurized line.
