Midland Industries 08640 Trailer Brake Tee Brass

Product Description

The MIDLAND INDUSTRIES 08640 is a nickel-plated brass trailer brake tee fitting designed for use in towed-trailer hydraulic brake line systems. It connects three brake line runs with two inverted flare ports and one male pipe thread port: a 1/4-inch inverted flare inlet, a 3/16-inch inverted flare outlet, and a 1/4-inch MPT port. The brass body with nickel plating resists corrosion in the wet, road-grime-exposed environment typical of trailer undercarriages. At 0.09 pounds, it is compact and lightweight, fitting into tight brake line routing layouts common on single- and tandem-axle trailers.

This fitting is used when splitting or distributing hydraulic brake line flow on towed trailers, including utility trailers, boat trailers, and equipment haulers equipped with hydraulic surge or electric-over-hydraulic brake systems. The mixed-size inverted flare ports allow the technician to transition between 1/4-inch and 3/16-inch brake line tubing within the same distribution point. Installation is typically performed by a brake or trailer service technician during brake line fabrication or repair.

Installation Notes

Installation should be performed by a qualified brake or trailer service technician. Depressurize the hydraulic brake system completely before disconnecting any brake line fittings. Use the appropriate inverted flare nut and tubing die set to ensure leak-free flare seats on both the 1/4-inch and 3/16-inch lines. Verify all connections for leaks before returning the trailer to service, in accordance with applicable federal motor vehicle brake system regulations.
