Stat-O-Seals 7/8in -10AN 2pk

The Stat-O-Seals 7/8in -10AN 2pk by EARLS represents a critical sealing solution for high-pressure hydraulic and fuel line systems found in race cars, custom vehicles, and performance applications. These specialized sealing washers are engineered to eliminate leaks at AN adapter connections where standard washers fall short. Two-pack format ensures you have a backup set for repairs, replacements, or multi-system installations without reordering.

Each Stat-O-Seal combines a 0.875-inch inside diameter aluminum washer with a bonded rubber O-ring, creating a dual-barrier seal that accommodates vibration and thermal cycling better than solid washers alone. The aluminum construction keeps weight minimal while providing rigidity, while the integrated O-ring compresses under AN fitting torque to create a positive fluid-tight seal. This hybrid design allows the seal to maintain integrity across repeated assembly and disassembly cycles—critical for race teams and builders who frequently service their systems. The 7/8-inch ID corresponds to -10AN male fittings, the industry standard for mid-to-large displacement fuel rails, transmission coolers, and oil system plumbing.

Performance shops, engine builders, and automotive enthusiasts standardize on EARLS Stat-O-Seals for leak-free -10AN connections in fuel injection systems, nitrous oxide circuits, and custom cooling loops. Install one washer on each side of your AN banjo fitting or adapter—the rubber O-ring faces the fitting body to seal against both the washer and port surface. Reusable across multiple builds, these washers should be inspected for O-ring condition during disassembly and replaced if the rubber shows hardening or visible damage. Buy this 2-pack for a complete system refresh or keep spares on hand for roadside repairs.
