PLC Union Connector - DOT 1/2" Push-to-Connect Air Brake Fitting - Parker 32PTC-8 177.12C628

Splice the big line back together with this PLC Union Connector distributed by FleetPro Parts & Tires. It joins two lengths of 1/2 in DOT air brake tubing with a push on each end — the heavy end of the plumbing, the runs that move the most air and drop the tanks the quickest when they are damaged. Nobody wants to pull and re-route an entire 1/2 in line because one section got crushed under a landing gear leg or worn through at a clamp. 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 Repair Without a Re-Plumb: The 1/2 in PLC Union Advantage

This push-to-connect (PLC) DOT air brake union uses a composite body with a brass collet and takes a 1/2 in tube end on each side. On the larger sizes a clean, square cut matters more than ever, and push-to-connect assembly rewards it: square the tubing, push it fully home, then tug-test both ends before airing the system back up. No flaring tool, no compression nut to crush the tube wall, no thread to dope.

Built for air brake plumbing on tractors and trailers, it meets FMVSS 571.106 / DOT requirements for brake circuits, so the joint is a permanent, inspectable repair rather than a get-home fix. At 0.05 lbs it costs nothing to keep a spare in the toolbox against the next one. At FleetPro Parts & Tires, this union is a direct replacement for highly searched industry numbers including Parker 32PTC-8, Tramec KV2H12-00, Tectran QL1362-8 and Sloan S762PMT-8.
