Coupler Cork

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. Choose Your Material 6061-T6 Aluminum Our standard Coupler Plug provides an excellent combination of durability, corrosion resistance and lightweight performance. 7075-T6 Aluminum For customers who want the premium option, our 7075 version provides substantially higher material strength while maintaining the same compact design.
