Midland Industries 770404A Brass Branch Tee 1/4 in

Product Description

The MIDLAND INDUSTRIES 770404A is a brass female branch tee fitting designed for push-to-connect pneumatic and fluid line applications meeting D.O.T. standards. It provides three connection points: two 1/4-inch push-in tube ports and one 1/4-inch female pipe thread (FPT) port, allowing a branch takeoff from an existing line without additional tools on the push-in connections. Rated to 150 psi and designed for temperatures from -40 to 200 degrees F, this fitting handles a wide range of service conditions. The all-brass construction resists corrosion and provides durability in both compressed air and compatible fluid systems.

This branch tee is suited for residential and light commercial applications where a push-to-connect D.O.T.-rated brass fitting is required. Typical installations include compressed air distribution lines, pneumatic control circuits, and fluid transfer systems where a fast, reliable branch connection is needed. The FPT port accepts a standard threaded pipe or fitting, making it easy to integrate into existing threaded assemblies. Plumbers, HVAC technicians, and pneumatic system installers commonly use this type of fitting when routing lines through equipment or control panels.

Compatibility

Designed as a D.O.T.-rated push-to-connect brass branch tee for use in compressed air and compatible fluid line systems requiring 1/4-inch push-in tube and 1/4-inch FPT connections.

Installation Notes

Installation is typically performed by licensed plumbers or HVAC technicians working on compressed air or pneumatic control systems. Depressurize and isolate the line completely before disconnecting or installing any fitting. Ensure the tube end is cut cleanly and squarely and is fully seated into the push-in port to achieve a proper seal. Apply thread sealant to the FPT connection per applicable IPC or IFGC guidelines for the service medium.
