What our customers are saying:

"John went out of his way to look up a supplier for me and even went into their inventory to verify that they had the same part. Even gave me the part number and the number on hand. Please acknowledge John for doing an outstanding job. He has provided service above and beyond anything expected."

Plumbing Adapter Fittings

Whatever your vehicle, our adapter fittings will help you convert the plumbing system to AN-style braided stainless hoses.

Note: AN, BSP, and NPT nomenclature can be confusing because the nominal sizes do not refer to the outside diameter of the threads. If you are not sure if you have AN, BSP, or NPT threads, check in our Threaded Fitting Guide.
