Midland Industries 710402SC Dot Male Run Tee Composite

Product Description

The MIDLAND INDUSTRIES 710402SC is a D.O.T.-rated composite male run tee designed for pneumatic push-to-connect tubing systems. It features two 1/4-inch push-to-connect ports on the run and a 1/8-inch male NPT branch port, allowing a straight tubing run to be tapped into a threaded port without cutting the line. The composite body keeps weight low while maintaining a 145 psi pressure rating. Rated for temperatures from -40 to 140 degrees F, this fitting suits air brake, pneumatic control, and fluid transfer applications where D.O.T. compliance is required. The positional swivel on the NPT port allows the branch to be oriented during installation without stressing the tubing.

This fitting is intended for use in air brake systems, pneumatic circuits, and auxiliary air lines on commercial vehicles and equipment. The push-to-connect ports accept standard 1/4-inch O.D. tubing for fast, tool-free tube insertion and release. The 1/8-27 male NPT thread connects to standard ports on valves, gauges, or manifolds. It is applicable in both OEM assembly and field service work on trucks, trailers, and industrial pneumatic equipment where D.O.T. compliance is required.

Compatibility

Designed as an OEM-style replacement or service fitting for D.O.T.-rated pneumatic push-to-connect systems using 1/4-inch O.D. tubing and 1/8-inch NPT ported components.

Installation Notes

Installation should be performed by a qualified technician familiar with D.O.T. air brake or pneumatic system service requirements. Depressurize and isolate the pneumatic circuit completely before removing or installing any fittings. Insert tubing straight and fully into the push-to-connect port until it seats; verify retention before repressurizing. Confirm the NPT port thread engagement is adequate and does not cross-thread before final tightening.
