This dust cap is fitted to the air outlet coupling on your ARB air compressor system. It’s the small rubber cap that protects the air fitting where you connect your hose. These caps are easily lost on the track or can split and perish from exposure. Without a cap, your air coupling is left open to dust, mud, and water, which can get pushed into the mechanism when you next connect your air line.
Running without a dust cap can lead to contaminated air entering your tyres, air lockers, or air tools. More importantly, it can damage the internal seals of the coupling itself, causing frustrating air leaks when you need your compressor the most.
Please check your existing ARB air coupling to confirm compatibility. Please contact us with your VIN details if you require further assistance to confirm fitment.
