Midland Industries 715304C Dot Male Run Tee Composite

Product Description

The MIDLAND INDUSTRIES 715304C is a D.O.T.-rated male run tee designed for pneumatic tubing systems that require a reliable inline branch connection. It features three ports: two 5/32-inch push-to-connect ends and one 1/4-inch male NPT center port, all housed in a composite body rated for 145 psi. The fitting carries a positional swivel function, allowing the NPT branch to be oriented before final lockdown. Rated for temperatures from -40 to 140 degrees F, it is suited for air brake, compressed air, and fluid transfer lines in mobile equipment and industrial applications. Licensed technicians and fleet mechanics are the typical installers.

This fitting is used in pneumatic plumbing runs where a branch tap off a main line is needed without cutting and rejoining tubing. The push-to-connect ends accept tubing with a simple insertion, speeding up assembly on air brake systems, pneumatic controls, and similar D.O.T.-compliant installations. The composite body keeps weight low while maintaining the pressure and temperature performance required for regulated mobile equipment circuits.

Key Features

• D.O.T.-rated composite body for use in regulated pneumatic and air brake systems
• Two 5/32-inch push-to-connect ports for fast, tool-free tubing insertion
• 1/4-inch male NPT branch port for integration into threaded fittings or valve bodies
• Positional swivel on the NPT port allows alignment before final tightening
• 145 psi maximum working pressure
• Operating temperature range of -40 to 140 degrees F

Compatibility

Designed as a D.O.T.-compliant replacement or new-installation fitting for composite push-to-connect pneumatic systems using 5/32-inch OD tubing with a 1/4-inch NPT branch connection.

Installation Notes

Installation is performed by qualified fleet mechanics or pneumatic systems technicians following applicable D.O.T. and vehicle air brake regulations. Depressurize the system fully before removing or installing any fitting. Ensure tubing is cut cleanly and squarely and inserted to full depth in each push-to-connect port before pressurizing. The NPT port should be thread-sealed with appropriate tape or sealant and torqued per standard pipe thread practice before final system pressurization and leak testing.
