Midland Industries 721006C Dot Male Branch Tee Composite

Product Description

The MIDLAND INDUSTRIES 721006C is a D.O.T.-rated composite male branch tee fitting designed for use in pneumatic and fluid distribution lines that require a reliable three-way connection. It features two 5/8-inch push-to-connect ports and one 3/8-inch male NPT port, allowing technicians to branch off an existing line without additional hardware. The composite body is rated to 145 psi and handles temperatures from -40 to 140 degrees F. A positional swivel on the NPT end simplifies routing in tight installations. This fitting is typically installed by fleet mechanics, plumbing contractors, and HVAC technicians working with air or compatible fluid lines.

The 721006C is suited for use in D.O.T.-compliant pneumatic systems, including commercial vehicle air lines, compressed air distribution, and light industrial fluid systems. The push-to-connect ports allow fast, tool-free tube insertion while the male NPT thread end provides a secure transition to threaded pipe or valve bodies. The positional swivel feature allows the NPT connection to be oriented as needed before final lock-down, reducing stress on adjacent tubing and fittings during assembly.

Key Features

• D.O.T.-rated composite body for use in regulated pneumatic applications
• Two 5/8-inch push-to-connect ports for fast, tool-free tube insertion
• 3/8-inch male NPT port for threaded pipe or valve body connection
• Positional swivel on NPT end allows flexible routing before final assembly
• Rated to 145 psi with an operating 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 and fluid distribution systems using 5/8-inch OD tubing and 3/8-inch NPT threaded connections.

Installation Notes

Installation should be performed by a qualified technician familiar with D.O.T. pneumatic system requirements and applicable pressure line codes. Depressurize the system fully before removing any existing fittings or inserting this tee. Ensure tubing is cut cleanly and squarely before inserting into push-to-connect ports to achieve a proper seal. Verify the NPT threaded end is tightened to the receiving port using appropriate thread sealant and confirm the swivel is positioned before final system pressurization.
