Nibco B067100 Cast Copper 90 Drop Ear Elbow 1 in

Product Description

The NIBCO B067100 is a cast copper 90-degree drop ear elbow designed for pressure piping applications in residential and commercial plumbing systems. This fitting connects a copper tube end (C) to a female threaded port (F), allowing a 90-degree change in direction while providing a flat mounting ear for securing the fitting to a wall or structural surface. Cast from copper alloy per ASTM B584, it delivers reliable performance in potable water, hydronic, and general-purpose pressure piping installations. Weighing 0.49 pounds, the B067100 is sized at 1 inch and suits work where a stub-out or shower arm needs a rigid, wall-anchored connection point.

This drop ear elbow is used primarily in rough-in plumbing work where a supply line terminates at a wall and must be anchored before a fixture, shower arm, or threaded adapter is connected. The mounting ear is fastened to framing or blocking to prevent pipe movement and stress at the connection point. Licensed plumbers and pipefitters install this fitting in new construction and remodel projects involving copper pressure systems. It is appropriate for both hot and cold water supply lines in residential and light commercial settings.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and depressurize the line before cutting, fitting, or soldering. Clean and flux all copper mating surfaces before soldering, and use lead-free solder where required by code for potable water systems. Fasten the mounting ear securely to solid blocking or framing to prevent movement at the fixture connection.
