The 6AN Male to 9/16-18 O-Ring Aluminum Black fitting from REDHORSE PERFORMANCE is a precision hose adapter engineered for custom fuel, oil, and coolant systems in performance vehicles and engine builds. This adapter serves as a critical transition component when connecting braided stainless steel hoses with AN-standard fittings to OEM or aftermarket ports threaded to 9/16-18 specifications.
Machined from lightweight aluminum alloy and finished in protective black anodize, the 6AN Male to 9/16-18 O-Ring adapter features a low-profile design that resists corrosion while maintaining minimal weight penalty in engine compartments. The male 6AN end accepts standard -6 braided hose, while the opposing 9/16-18 port threads feature an integrated o-ring seal that eliminates the need for additional sealing tape or dope compounds—a design that reduces assembly time and ensures a leak-proof dry-break connection.
Mechanics and fabricators building LS, EJ, or inline-four performance engines will find this REDHORSE fitting indispensable when OEM port sizes don't align. The compact form factor and lightweight design make it ideal for tight spaces common in modern engine bay layouts, from fuel rails to turbo feed lines.
