Brass DOT Male Branch Tee - Two 3/8in Tube Ends x 1/4in NPT Male - Eaton 1472X6 177.14726B

Tap a live air line without cutting into it using this DOT brass male branch tee distributed by FleetPro Parts & Tires. It carries two 3/8in tube ends that connect opposite each other plus a 1/4in NPT male branch, so a gauge line, pressure switch, sender or small accessory circuit picks up off an existing run through one fitting instead of a splice. A tee that seeps is the leak nobody finds on the first pass: the compressor cycles nonstop, the low-air buzzer nags at idle, and the truck airs down sitting in the yard 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.

Two Runs and a Branch in One Fitting: The 1/4in NPT Branch Tee Advantage

Both run legs take 3/8in DOT nylon air brake tubing and connect opposite each other, so the tee drops into an existing line without re-routing the run to make room for it. The branch is a full 1/4in NPT male thread, which is the size most air gauges, low-pressure switches and accessory ports already use, so the component threads straight into the tee instead of sitting on top of an adapter bushing. Every bushing you delete is one less sealing surface waiting to weep.

The brass body handles the moisture, oil carryover and road salt that circulate through a heavy-duty air system, and this fitting meets FMVSS 571.106 / DOT requirements for brake circuits, not just shop air. At FleetPro Parts & Tires, we know the fitting count is the leak count. This Automann tee replaces 177.8051 and is a direct replacement for the highly searched industry number Eaton 1472X6. It ships new with a 1-Year FleetPro Warranty.
