Nibco B074150 Cast Copper 90 Elbow 3/4 Inch C X C

Product Description

The NIBCO B074150 is a cast copper 90 degree Hy-Set elbow designed for sweat-connect pressure piping systems. It features a C x C (copper-to-copper) end connection, allowing installation using standard soldering or brazing techniques. At 3/4 inch fitting size, it is suited for residential and light commercial water distribution, hydronic heating, and general plumbing pressure lines. Licensed plumbers and pipefitters install this fitting as part of new construction rough-in work or repair and remodel projects where a 90 degree direction change is required in a copper pressure system. The cast copper construction provides reliable pressure-rated performance in both hot and cold water applications.

This elbow is used in 3/4 inch copper pressure piping systems across a range of applications including potable water supply, hydronic radiant or baseboard heating loops, and general mechanical piping. It is appropriate for residential and light commercial installations where a 90 degree turn is needed in a sweat-connected copper line. The Hy-Set design is intended for use with standard copper tubing and compatible flux and solder or brazing alloy per applicable codes.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC or local plumbing code requirements. Shut off and depressurize the water or hydronic system and fully drain the line before cutting or fitting any copper pipe. Clean the tube ends and fitting sockets thoroughly with emery cloth or fitting brush, apply appropriate flux, and sweat-solder or braze the joint per code. Do not apply heat to a pressurized or water-filled line.
