Nibco B056050 Cast Copper 90 Elbow 1-1/4 X 3/4 in C X C

Product Description

The NIBCO B056050 is a cast copper 90-degree close rough elbow designed for pressure piping systems in residential and commercial plumbing applications. The fitting connects 1-1/4-inch and 3/4-inch copper tubing using a sweat (C x C) end connection on both ends. Cast copper construction provides consistent wall thickness and reliable joint integrity under system pressure. This elbow is used where a 90-degree directional change is required in a tight rough-in space, making it a standard choice for licensed plumbers working with copper distribution systems.

This fitting is suited for potable water supply lines, hydronic heating distribution piping, and general pressure piping where copper-to-copper sweat connections are specified. The close rough configuration is commonly used in wall or ceiling rough-in work where minimal fitting length is needed. Plumbing contractors and service technicians select this elbow when transitioning between 1-1/4-inch and 3/4-inch copper lines in a single 90-degree change of direction.

Key Features

• Cast copper construction for consistent wall thickness and strong brazed or soldered joints

• C x C (sweat) end connections on both ends for standard copper tubing
• Reducing configuration: 1-1/4 inches on one end, 3/4 inches on the other
• Pressure fitting rated for use in water supply and hydronic pressure piping systems

Compatibility

Designed as an OEM-style pressure fitting for use with standard copper tubing in residential and commercial plumbing systems where C x C sweat connections are required.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the supply line and drain the pipe before cutting or fitting. Clean and flux both the pipe ends and fitting sockets before soldering or brazing to ensure a leak-free joint. Do not apply heat to the fitting while the line is under pressure or contains water.
