XRP's air conditioning hose is an innovative, patent-pending design, we think will appeal to discriminating motorsports enthusiasts. We evaluated many types of A/C hose but found this one, manufactured by Eaton, to be the best. Comprised of attractive stainless steel outerbraid with an inner tube of nylon, the way it handels refrigerant is simply superior. Pair it, with eye-catching nickel plated steel reusable fittings, available with charge ports and you've got assemblies that are easy to install and service anywhere.
