-10 Replacement Nitrile O-Rings (10)

The -10 Replacement Nitrile O-Rings (10) from AEROMOTIVE are essential sealing components designed for fuel system modifications, carburetor tuning kits, and high-performance fuel delivery systems. These o-rings are crucial for anyone involved in rebuilding fuel pressure regulators, servicing AN fittings, or maintaining custom fuel manifolds.

Constructed from nitrile (NBR), these o-rings offer excellent resistance to gasoline and common fuel additives, ensuring durability across typical engine bay temperatures. The -10 designation indicates compatibility with -10 AN hose fittings and port adapters, making them a reliable choice for various fuel applications. Their nitrile material resists petroleum degradation better than silicone, providing superior compression set retention over time.

Fuel system builders, engine swap enthusiasts, and carb-to-EFI conversion specialists can rely on these o-rings to prevent 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 leaks.
