The ARB bulkhead kit adapts 5mm fittings to 3.5mm O-ring type connections and is supplied for use in air and breather plumbing. These bulkhead adaptors allow secure through-panel feedthroughs where tubing or fittings need a sealed passage. Install the kit when routing air lines or breather hoses through mounts to maintain proper sealing and tidy hose runs.
