What our customers are saying:

"You guys are SOOOOOO cool! Real parts, excellent prices, and customer care way beyond the call of duty. The six bucks shipping refund isn't the issue. The fact that you refunded it, and notified me, proves your caliber. Not to forget that you had arcane items IN STOCK, or that your website permits "quick ordering", or that your PAPER catalog has excellent and clear info!"

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.
