Nibco B070600 Cast Copper 90 Elbow 1-1/4 in C X M

Product Description

The NIBCO B070600 is a cast copper 90 degree elbow fitting designed for pressure piping systems in residential and commercial plumbing and mechanical applications. It connects copper tubing using a solder-cup (C) inlet to a male (M) threaded outlet, making it useful where a sweat connection must transition to a threaded joint. At 1-1/4 inches fitting size, it handles common supply and distribution line sizes. Cast copper construction provides reliable pressure ratings and corrosion resistance typical of copper pressure fittings. Licensed plumbers and pipefitters are the primary installers. The fitting meets ASTM B584 and ISO standards.

This fitting is suited for potable water supply lines, hydronic heating distribution piping, and general pressure piping systems where a 90 degree directional change is needed. It is appropriate for both new construction rough-in and retrofit or repair work. The C x M end connection is commonly used when connecting to existing threaded components such as valves, nipples, or threaded adapters while maintaining a soldered joint on the copper tubing side.

Key Features

• 90 degree elbow geometry for right-angle direction changes in pressure piping runs
• Cast copper construction meets ASTM B584 for cast copper alloy fittings
• C x M end connection allows sweat-to-male-thread transition in a single fitting
• 1-1/4 inch fitting size suits common residential and light commercial distribution lines
• Pressure fitting style rated for standard potable water and hydronic system operating conditions
• Complies with ISO standards in addition to ASTM B584

Compatibility

Designed as an OEM-style pressure fitting for use with 1-1/4 inch copper tubing in standard pressure piping systems where a solder cup to male thread connection is required.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable edition of the IPC or local plumbing code. Shut off and depressurize the water supply and drain the line before cutting or soldering. Clean and flux all mating surfaces before applying heat; use lead-free solder where required by code for potable water service. Do not over-heat the fitting during soldering, as excessive heat can damage the fitting material.
