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.
