Push-to-Connect Union Tee - DOT 1/2" Air Brake Tube Fitting - Parker 364PTC-8 Tectran QL1364-8 177.12C648

Branch a heavy air line without cutting the whole run apart with this DOT Push-to-Connect (PLC) Union Tee distributed by FleetPro Parts & Tires. It joins three 1/2 in air brake tube ends in a single leak-tight junction — the larger tube size trucks use where volume matters and a restriction is the last thing you want. A weeping or badly seated air fitting bleeds pressure all day: the compressor cycles nonstop, the low-air warning keeps the driver guessing, and a leaking brake circuit is an instant out-of-service at the scale. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Full-Flow Junction: The 1/2 in DOT Union Tee Advantage

This Automann fitting pairs a composite body with a brass collet. The composite housing resists the road salt, spray and moisture that pit all-metal fittings, while the brass collet grips the tube where it counts. Assembly is push-to-connect: push the tube home, the collet locks, and there is no flaring, no compression sleeve to tighten and no torque wrench needed on the shoulder. All three legs take the same 1/2 in tube, so one part number finishes the junction instead of a handful of adapters.

The tee is built to the FMVSS 571.106 / DOT requirements that govern brake circuits, which is exactly what a roadside inspector is looking for. At FleetPro Parts & Tires, we know a brake job is only right when every joint holds. This union tee is a direct replacement for highly searched industry numbers including Parker 364PTC-8, Sloan S764PMT-8, Tramec KV2T13-00, Tectran QL1364-8 and Velvac 016980, and it is backed by our 1-Year FleetPro Warranty.
