Midland Industries 77504 Copper Sweat Tee 1-1/4 in

Product Description

The MIDLAND INDUSTRIES 77504 is a full-size copper sweat tee fitting used to create equal-branch splits in copper pipe systems. All three connections measure 1-1/4 inches and accept standard C (sweat/solder) joints, making this a straight equal tee configuration. Rated to 500 psi and suitable for temperatures from 32 degrees F to 200 degrees F, it meets the pressure and thermal demands of residential and light commercial plumbing and hydronic heating lines. Licensed plumbers and pipefitters install this fitting during new construction and retrofit work where a copper branch connection is required.

This fitting is used in potable water distribution, hydronic heating loops, and general plumbing applications where copper sweat connections are specified. Its equal 1-1/4 inch port sizing makes it appropriate for main-line branch runs, boiler supply and return piping, and similar systems requiring consistent flow diameter through all three outlets. The sweat connection type requires flux and solder applied to cleaned pipe and fitting surfaces before heating with a torch.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off and depressurize the water or heating system and drain the affected lines before cutting in the fitting. Clean all pipe ends and fitting sockets with emery cloth or a pipe brush, apply lead-free flux, and sweat-solder joints per applicable plumbing code requirements including IPC and local amendments. Avoid applying heat directly to the fitting body for extended periods, as overheating can damage the copper and compromise joint integrity.
