Push-to-Connect Union Tee - DOT 3/8" Air Brake Tube Fitting - Parker 364PTC-6 Tectran QL1364-6 177.12C646

Splice a third air line into a working brake circuit with this DOT Push-to-Connect (PLC) Union Tee distributed by FleetPro Parts & Tires. It joins three 3/8 in air brake tube ends in one leak-tight junction, so branching a circuit does not mean rebuilding the whole run. A cracked, weeping or badly seated air fitting bleeds pressure all shift long — the compressor never stops cycling, the low-air buzzer nags the driver, 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.

Leak-Free Air Plumbing: The DOT Union Tee Advantage

This Automann fitting pairs a composite body with a brass collet. The composite housing shrugs off the road salt, spray and moisture that pit all-metal fittings, while the brass collet does the gripping where it counts. Assembly is push-to-connect: the tube goes in, the collet locks it, and there is no flaring, no compression sleeve and no torque wrench needed on the shoulder. Because all three legs take the same 3/8 in tube, one part number covers the junction instead of a bag of adapters.

The tee is built to the FMVSS 571.106 / DOT requirements that govern brake circuits, so it belongs on the truck and not just in the shop drawer. 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-6, Sloan S764PMT-6, Tramec KV2T11-00, Tectran QL1364-6 and Velvac 016960, and it is backed by our 1-Year FleetPro Warranty.
