When a compressor is mounted in an inaccessible location, such as under the truck bed, our under-truck air compressor system provides a great solution. It mounts a coupler to a panel or frame member via a bulkhead fitting, and provides several special features, such as an adjustable pressure switch, a stainless steel braided hose assembly, and all necessary couplers, fittings, wire, and terminals.
