AN Fittings & Hoses

The Ace Race Parts brand of Hose End Fittings and Adapter Fittings offers reliable, smooth-flowing connections for a wide variety of plumbing and fluid delivery applications. All our hose end fittings are precision CNC-machined from 6061 Aluminum, feature a double PTFE O-ring design to create a leak-free seal, and are offered with a durable polished black hard-anodized finish. Our Hose End Fittings are available in a wide range of configurations and sizes, from -4AN to -20AN, and are suitable for use with coolant, fuel, oil, and vacuum applications.

Pair our Aluminum Hose End Fittings with our Stainless Steel Braided and Nylon Braided Flexible Race Hoses. All our flexible race hoses are E85 compatible and safe for use in various applications, including fuel systems (E85/E10 compatible), methanol, oil, lubricants, coolant systems, and vacuum systems.

Our high-pressure and abrasion-resistant Stainless Braided Flex Hose features a 300-series Stainless Steel double-braided exterior, a braided nylon liner, and a reinforced synthetic rubber inner liner, and has a safe operating pressure of 1,000 psi.
