PLC Swivel Male Run Tee - DOT 3/8" Tube x 3/8" NPT Air Brake Fitting - 371PTC66 QL13716C 177.12C716C

Tee a new air line into an existing run without cutting the whole circuit apart. This PLC Swivel Male Run Tee distributed by FleetPro Parts & Tires is a DOT push-to-connect fitting that joins 3/8in nylon air-brake tubing to a 3/8in NPT male port, and the swivel body lets you clock the fitting where the line wants to sit instead of where the threads happen to stop. A weeping or badly seated air fitting bleeds the supply tank down overnight, keeps the compressor cycling, robs the brakes of recovery time and hands you an out-of-service sticker at the next roadside 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.

Leak-Free Air, Faster: The PLC Swivel Run Tee Advantage

Push-to-connect is the reason a job that used to mean flare tools, ferrules and a wrench jammed against a frame rail is now a clean push. Square-cut the nylon tube, push it into the collet until it bottoms, and the brass collet bites the tube and seals the joint. The composite body keeps weight and price down while the brass does the holding, so this is real air-brake hardware at a number that lets you keep spares in the drawer instead of a single one on the truck. The swivel is the detail a tech appreciates at 2 a.m.: thread the fitting home properly, then turn the tube ports to face the run without unwinding the seal you just made.

This is a DOT fitting built specifically for nylon air-brake tubing, so it belongs on the brake circuit rather than in the general-purpose brass drawer. It serves as a direct replacement for highly searched industry numbers including 371PTC66, QL13716C, 016403 and S771PMT66.
