Overview

Take a branch off a large air line without cutting the run using this DOT brass push-to-connect male branch tee distributed by FleetPro Parts & Tires. It carries two 1/2in tube ends that connect opposite each other and a 1/4in NPT male swivel branch, so a 1/2in supply can feed a valve, gauge or accessory port while the main run stays intact. A tee that seeps is one of the hardest leaks on a truck to find and one of the easiest to fix โ€” it quietly runs the compressor to death, trips the low-air warning at idle, and airs the truck down overnight. Manufactured by Automann to Fleet Standard specifications, 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.

Big-Line Branching: The 1/2in Push-To-Connect Tee Advantage

Both run legs are push-to-connect (PLC), so 1/2in DOT nylon air brake tubing seats with a straight push and locks โ€” a real advantage on heavy 1/2in line, which is stiff, awkward to hold and miserable to assemble with compression nuts under a chassis. The brass body and collet mean the gripping hardware is brass too, not plastic, so the joint keeps its bite through heat cycles, vibration and winter road salt.

The 1/4in NPT male swivel branch threads into its port at full torque and then rotates, letting you square the two 1/2in tube legs to the run instead of twisting stiff tubing to meet a fixed tee. This fitting meets FMVSS 571.106 / DOT requirements for brake circuits, so it is legal in a service or emergency line rather than shop air only. At FleetPro Parts & Tires, we know most air system chases end at a fitting. Order it by the Automann distributor number, 177.13B728B, and it ships new with a 1-Year FleetPro Warranty.
