Overview

An open port on an air brake circuit is a system that will not build pressure, and a truck that will not build pressure is a truck that does not move. This Nylon Push-to-Connect (PLC) Plug distributed by FleetPro Parts & Tires seals unused PLC ports on 3/8 in tube fittings, cleanly and without tools. 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.

Close It Off Properly: The 3/8 in PLC Plug Advantage

The 3/8 in ports are the big ones on the truck, the supply and reservoir side of the plumbing, and an improvised cap there leaks under exactly the pressure you need most. This is a nylon push-to-connect plug for 3/8 in ports that pushes in by hand and holds like the tube it replaces. It meets FMVSS 571.106 and DOT requirements for brake circuits, which is the difference between a repair that passes inspection and one that does not.

Manufactured by Automann to Fleet Standard specifications and used in air brake plumbing on tractors and trailers, this plug is a direct replacement for highly searched industry numbers including Parker 639PMT6 and Volvo/White 8077187. At 0.1 lbs there is no reason not to keep a handful in the toolbox.
