Package of 10 -8AN Rubbe r O-Rings

The VIBRANT PERFORMANCE Package of 10 -8AN Rubber O-Rings (Part No. 20888) is a critical component set for fluid system assembly, designed for high-pressure hydraulic, fuel, and coolant line connections. These FKM elastomer o-rings are engineered to maintain reliable sealing across a wide range of temperatures and fluid types, making them essential for performance fuel systems, custom cooling loops, and automotive aftermarket builds where precision fluid containment is non-negotiable.

The -8AN size designation refers to the AN (Army-Navy) standard metric equivalent, specifying the inner diameter of the o-ring to ensure compatibility with -8AN hose fittings, adapters, and manifold ports used throughout the automotive performance industry. FKM (Viton) material provides superior chemical resistance compared to standard Buna-N, resisting petroleum products, synthetic oils, and coolants while maintaining elasticity under sustained heat. This 10-count package provides the redundancy professional builders and serious enthusiasts need when assembling or servicing multiple fuel and coolant circuits, or when maintaining spares for field repairs.

Technicians working on turbocharged fuel systems, custom cooling setups, transmission cooler lines, and high-flow fuel rails routinely stock AN o-ring assortments to avoid downtime from failed seals. The -8AN size is common across mid-size fuel line applications, pressure relief ports, and sensor fittings in both street and competition vehicles. Carrying a verified set of OEM-quality replacement o-rings ensures that leaks are remedied quickly without compromising system integrity or safety.
