NIBCO 907 3-Inch Copper Elbow

The NIBCO 907 is a wrot copper 90-degree drop elbow designed for sweat fitting connections. It joins two 3-inch copper tubes with cup ends on both sides. The fitting handles air and potable water applications at a maximum operating pressure of 5 psi and temperatures up to 400 degrees F. It meets ASME B16.29 and ASTM B75 standards.

Suits standard 3-inch copper plumbing

This elbow suits installers joining 3-inch copper tube in residential or commercial water and air lines where a 90-degree change of direction is required. It is not for systems operating above 5 psi or 400 degrees F. Buyers needing a different angle, a reducing connection, or a threaded joint should look at other fitting types.

Sweat cup connection on both ends

The defining specification is the double cup connection for sweat soldering onto 3-inch copper tube. This joint method requires soldering skill and clean tube ends. If the installation calls for press, push-fit, or threaded connections, this fitting will not work.
