Midland Industries 715302C Dot Male Run Tee Ptc X Npt

Product Description

The MIDLAND INDUSTRIES 715302C is a D.O.T.-rated composite male run tee designed for pneumatic tubing systems in commercial vehicle and industrial air brake applications. It combines two 5/32-inch push-to-connect ports with a 1/8-inch male NPT center port in a run-tee configuration, allowing a branch connection without interrupting the main line. The composite body is rated to 145 psi and operates across a temperature range of -40 to 140 degrees F. A positional swivel feature on the NPT branch simplifies alignment during installation. Licensed plumbers, fleet mechanics, and pneumatic system technicians are the typical installers.

This fitting is suited for D.O.T.-compliant air brake and pneumatic control lines on trucks, trailers, and heavy equipment. The push-to-connect ports accept 5/32-inch OD tubing for fast, tool-free connections, while the 1/8-inch male NPT port threads directly into a manifold, valve body, or ported component. The composite construction reduces weight compared to all-brass fittings and resists corrosion in exposed under-vehicle environments. It is appropriate for both new plumbing runs and service replacements in fleet maintenance shops.

Key Features

• D.O.T.-rated construction meets air brake system compliance requirements
• Dual 5/32-inch push-to-connect ports allow tool-free tubing insertion and release
• 1/8-inch male NPT branch port for direct threaded connection to valves or manifolds
• Positional swivel on NPT port simplifies alignment in tight routing situations
• 145 psi maximum working pressure rated for pneumatic service
• Composite body rated from -40 to 140 degrees F for under-vehicle temperature exposure

Compatibility

Designed as a D.O.T.-compliant replacement or new-installation fitting for pneumatic tubing runs using 5/32-inch OD push-to-connect tubing with a 1/8-inch NPT threaded branch connection point.

Installation Notes

Installation should be performed by a qualified mechanic or pneumatic systems technician familiar with D.O.T. air brake regulations. Depressurize the pneumatic system completely before removing or installing any fitting. Ensure tubing is cut square and fully seated in the push-to-connect ports before pressurizing. Apply appropriate thread sealant to the NPT port and verify there are no leaks at operating pressure before returning the system to service.
