#8 Male To #10 O-Ring Bo

The #8 Male to #10 O-Ring Straight Adapter is an essential AN (Army-Navy) hose fitting for high-performance marine fuel systems, hydraulic lines, and pressurized applications on modern boats and racing vessels. This fitting bridges two different AN port sizes—stepping from #8 to #10—allowing flexibility in system design where port mismatches would otherwise require complete line replacement or custom fabrication. Built by XRP-XTREME RACING PRODUCTS, a trusted manufacturer in motorsports and marine fluid handling, this adapter is engineered for reliability under demanding conditions.

Constructed from black anodized aluminum, the #8 Male to #10 O-Ring adapter combines corrosion resistance with lightweight durability—critical for saltwater and freshwater boating environments where oxidation degrades steel fittings rapidly. The male-to-male straight design ensures leak-free connections via an O-ring seal rather than traditional thread-type compression, providing superior hold-down performance under vibration and thermal cycling. Anodized aluminum finishes withstand UV exposure and salt spray while maintaining easy visual inspection for wear or degradation, and the compact 2.75 x 1.3 x 3.55-inch profile allows installation in tight engine compartments.

Anglers and boaters upgrading fuel delivery, water cooling, or hydraulic systems benefit most from this adapter when transitioning between components with different AN port sizes. Installation requires compatible AN fittings on both ends and a proper O-ring seated in the #10 female port; most marine mechanics and experienced boat builders can install in minutes using standard wrenches. XRP's reputation in racing and marine applications ensures this fitting meets or exceeds industry standards for pressure rating and cycle life, making it suitable for both stock and modified engine packages.
