Seamless AN to Hardline Conversion: Effortlessly connect a standard 6AN male flare fitting (9/16"-18 UNF threads) to 5/16" OD hardline tubing, ensuring a precise and secure fit for automotive fuel, oil, and fluid systems.
Durable Corrosion-Resistant Build: Constructed from high-strength aluminum alloy with a brass ferrule, this adapter offers superior resistance to fuels, oils, coolants, and harsh automotive environments for long-lasting performance.
Leak-Free High-Pressure Seal: Features a 37° AN flare (JIC 37°) metal-to-metal seal, designed to withstand high pressure and vibrations while preventing leaks in demanding applications.
Versatile Multi-System Compatibility: Ideal for fuel lines (gasoline, diesel, ethanol), oil coolers, power steering, transmission coolers, and water/methanol injection setups, providing reliable connections across various automotive systems.
Engineered exclusively for use with rigid tubing such as stainless steel or aluminum hardline. Note: Not compatible with soft nylon or rubber hose.
