Don't Leave Your Air Coupler Wide Open.
Your onboard air system lives where dirt, mud, dust, sand and water are part of the territory. An exposed quick-connect coupler gives all of it somewhere to go.
The CMM Offroad Coupler Plug provides a simple, purpose-built way to protect an unused female air coupler until you're ready to connect your hose.
Precision CNC-machined in the USA, the Coupler Plug snaps directly into a compatible female quick-connect fitting just like the mating air fitting would. Once installed, it helps prevent contaminants from reaching the internal components of the coupler.
