Overview

Put a cut air line back together in minutes with this PLC Union Connector distributed by FleetPro Parts & Tires. It joins two lengths of 1/4 in DOT air brake tubing with a push on each end, which is the fastest legal way to deal with a line that has been chafed through on a crossmember, nicked by a tire carcass, or cut short during a repair. A weeping 1/4 in line bleeds the tanks down overnight, keeps the compressor loading, and turns into a low-air buzzer on the first cold start. 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.

A Legal Splice in Two Minutes: The 1/4 in PLC Union Advantage

This is a push-to-connect (PLC) DOT air brake union with a composite body and a brass collet, built for a 1/4 in tube end on each side. The brass collet is what grips the tubing and holds it against system pressure, while the composite body keeps the fitting light and easy to work with in a tight run. There is no flaring tool, no compression nut to crush the tube, and no thread to seal โ€” cut the tube square, push both ends home, and tug-test the joint.

It is built specifically for air brake plumbing on tractors and trailers and meets FMVSS 571.106 / DOT requirements for brake circuits, so the splice belongs in a service or emergency line rather than being a temporary patch that has to come out before the next inspection. At 0.02 lbs, a handful lives easily in the toolbox. At FleetPro Parts & Tires, this union is a direct replacement for highly searched industry numbers including Parker 32PTC-4, Sloan S762PMT-4, Tramec KV2H07-00 and Tectran QL1362-4.
