Midland Industries 77128 90 Deg Street Elbow 3/4 in Copper

Product Description

The MIDLAND INDUSTRIES 77128 is a 90-degree solder joint street elbow designed for copper sweat piping systems. One end accepts a fitting connection and the other end is a plain copper spigot that inserts directly into a standard copper fitting socket, eliminating the need for an additional coupling at the turn. Constructed from wrot copper, this elbow is rated to 500 psi and handles temperatures from 32 degrees F to 200 degrees F. It is sized at 3/4 inch for both connection ends, with a 7/8 inch OD, and is suitable for potable water, hydronic heating, and general plumbing distribution lines. Licensed plumbers and pipefitters are the primary installers.

This fitting is used in residential and light commercial plumbing applications where a 90-degree directional change is needed within a copper sweat piping system. Its street configuration is especially useful in tight spaces or retrofit situations where reducing the total number of fittings at a joint is a priority. Typical installations include supply lines, branch connections, and riser transitions in water distribution systems. The compact dimensions of 1.65 inches in length and 1.85 inches in width make it easy to work with in confined areas.

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 drain the water supply completely before cutting into any existing line. Clean and flux all mating surfaces before soldering, and use lead-free solder where required for potable water applications. Allow the joint to cool fully before restoring system pressure.
