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 1/4 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 1/4 in PLC Plug Advantage

Every time a line gets rerouted, a valve gets deleted or an accessory comes off, a port is left open. The temptation is to improvise. The correct answer is a plug built for the fitting, and this one is: a nylon push-to-connect plug for 1/4 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 639PMT4 and Volvo/White 8077186. At 0.1 lbs there is no reason not to keep a handful in the toolbox.
