Overview

Pick up a branch line off an existing air run in minutes with this PLC Swivel Male Branch Tee distributed by FleetPro Parts & Tires. It is a DOT push-to-connect fitting that ties 3/8in nylon air-brake tubing into a 3/8in NPT male port, and because the threaded end swivels you can seat it correctly and still point the tube ports the way the harness runs. Air fittings are the quiet killers of a brake system: a slow seep at one joint drains the tanks overnight, keeps the governor cycling all shift, stretches recovery time between brake applications and shows up as a defect on the next DOT inspection. 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.

One Clean Push: The PLC Swivel Branch Tee Advantage

The push-to-connect design takes the specialist tooling out of an air-line repair. The tube is cut square, pushed into the collet until it bottoms, and the brass collet grips and seals it without flares or ferrules. Automann builds the fitting on a composite body with that brass collet doing the work, which keeps the part light and affordable enough to buy in multiples rather than one at a time. That matters on a tee, because a branch tee is rarely the only fitting a repair needs.

This is a DOT fitting made for nylon air-brake tubing, so it goes on the brake circuit with confidence instead of the general-purpose hardware you keep for shop air. It serves as a direct replacement for highly searched industry numbers including 372PTC66, QL13726C, 016366 and S772PMT66.
