-10 Replacement Nitrile O-Rings (10)

The -10 Replacement Nitrile O-Rings (10) from AEROMOTIVE are essential sealing components for fuel system modifications, carburetor tuning kits, and high-performance fuel delivery systems. Whether you're rebuilding a fuel pressure regulator, servicing AN fittings, or maintaining a custom fuel manifold, these o-rings provide reliable, long-lasting seals that prevent fuel leakage and system contamination. A 10-pack ensures you have spares on hand for multiple projects or future maintenance cycles.

AEROMOTIVE's nitrile construction offers excellent resistance to gasoline and common fuel additives while maintaining durability across typical engine bay temperatures. The -10 designation refers to the AN (Army-Navy) standard size, which is compatible with -10 AN hose fittings and port adapters commonly found in custom fuel systems, carburetors, and EFI conversions. Nitrile material is the industry standard for fuel applications because it resists petroleum degradation better than silicone and provides superior compression set retention over time, ensuring seals remain tight through thermal cycling and pressure fluctuations.

Fuel system builders, engine swap enthusiasts, and carb-to-EFI conversion specialists rely on these o-rings to eliminate weeping fuel leaks at manifold connections, regulator ports, and dampener unions. Installation is straightforward: lubricate lightly with fuel or assembly grease, seat in the groove or port, and tighten the fitting hand-snug plus ¼ turn to avoid over-compression. Keep a 10-pack in your toolbox for quick repairs or as spares when troubleshooting fuel delivery issues—a small investment that prevents costly fuel contamination and system downtime.
