The Aeroflow AERFCM3476 #10 O-Ring is a sealing component sized for -10 AN hydraulic, pneumatic, and fluid transfer connections. It is widely used in automotive fuel systems, aftermarket turbo installations, brake line plumbing, and custom cooling circuits where a reliable seal at threaded fittings is required. This o-ring meets the dimensional standards expected by professional builders and performance enthusiasts.
The seal operates by compressing between the fitting face and its mating surface, creating a barrier that prevents fluid migration under both static and dynamic pressure conditions. The elastomer compound is selected for its resilience across the temperature ranges found in engine compartments, from cold startup to sustained high-temperature operation. This flexibility allows the o-ring to accommodate minor surface imperfections while maintaining a consistent seal.
Technicians who regularly assemble or service AN-based plumbing systems appreciate having the correct o-ring size available at the workbench. Using the proper #10 seal eliminates the common problems associated with oversized or undersized substitutes, such as slow weeping, extrusion, or incomplete compression. This o-ring is a small but essential component that contributes directly to the safety and reliability of high-performance fluid systems.
