Midland Industries 77500 Copper Reducing Tee 1x3/4x1/2 in

Product Description

The MIDLAND INDUSTRIES 77500 is a copper reducing tee fitting used to join and redirect flow in copper sweat piping systems where three different pipe sizes meet at a single junction. It connects a 1-inch run on the main line to a 3/4-inch outlet and a 1/2-inch branch, all using sweat (solder) connections. Rated to 500 psi and suitable for service temperatures from 32 to 200 degrees F, this fitting handles both domestic water supply and hydronic distribution applications. Plumbers and pipefitters install it wherever a main supply line needs to step down to smaller branch lines in a single fitting.

This reducing tee is suited for residential and light commercial plumbing where copper sweat piping is standard. Typical installations include domestic hot and cold water distribution systems, radiant heating supply and return manifolds, and similar closed-loop piping configurations. The three-port reducing geometry eliminates the need for separate reducers and a standard tee, simplifying the fitting count at the connection point.

Key Features

• Three-size reducing configuration: 1 inch x 3/4 inch x 1/2 inch, all sweat connections
• 500 psi pressure rating for demanding water supply and hydronic service
• Operating temperature range of 32 to 200 degrees F
• Full copper construction for corrosion resistance and long service life
• Sweat (solder) end connections compatible with standard copper tubing and fittings practices

Compatibility

Designed as an OEM-style replacement or new-installation fitting for copper sweat piping systems using standard Type L or Type M copper tubing in 1-inch, 3/4-inch, and 1/2-inch nominal sizes.

Installation Notes

Installation is performed by a licensed plumber or pipefitter familiar with copper sweat soldering techniques. Shut off and drain the supply line completely before cutting into existing piping. Clean and flux all mating surfaces before soldering, and follow local plumbing codes and IPC guidelines for solder alloy selection, particularly in potable water systems where lead-free solder is required. Allow the joint to cool fully before restoring pressure.
