O-Ring and Seal Kit for Shutoff 8an Gas and Alky

The O-Ring and Seal Kit for Shutoff 8AN Gas and Alky by ENDERLE is purpose-built for high-performance fuel system applications where precision sealing is non-negotiable. This kit is essential for mechanics and enthusiasts working with fuel shutoff systems on nitrous oxide and alcohol-injected engines, where extreme pressure cycles and chemical compatibility demand superior sealing integrity. Whether you're rebuilding a carbureted drag racing engine or servicing a blown alcohol funny car, this seal kit ensures your shutoff valve maintains perfect pressure retention across multiple heat cycles and fuel types.

ENDERLE's O-ring and seal kit utilizes elastomer compounds specifically formulated to resist alcohol and nitromethane degradation—critical for fuel systems running methanol blends or full nitro fuel. The 8AN (8/16-inch) port specification matches industry-standard fuel line sizing in competition fuel delivery systems, ensuring compatibility with ENDERLE shutoff valves and related flow control components. These seals are engineered to maintain their compression set across the thermal extremes of high-boost engines, preventing fuel weeping or catastrophic pressure loss during competition or street use.

Professional drag racers, circle track teams, and dedicated street car builders rely on this seal kit to prevent mid-run fuel system failures caused by worn or degraded elastomers. Installation is straightforward for anyone with carburetor or fuel system rebuild experience—simply disassemble the shutoff valve body, replace the worn seals with fresh O-rings from this kit, and reassemble. Regular replacement during major engine rebuilds or annual competition maintenance intervals ensures your fuel shutoff valve remains pressure-rated and eliminates potential lean-out conditions caused by fuel bypass around failed seals.
