AN Cap -10

The ALLSTAR PERFORMANCE AN Cap -10 is an aluminum AN fitting cap engineered for high-pressure fluid line systems in motorsports, hydraulic, and pneumatic applications. This black anodized cap provides a sealed termination for -10 AN ports, preventing fluid leakage and contamination in demanding engine compartment and chassis environments where reliability under vibration and temperature cycling is critical.

Manufactured from aluminum and anodized for corrosion resistance, the -10 AN cap fits standard AN10 port threads used throughout performance fuel systems, transmission coolers, and power steering circuits. The black anodized finish resists oxidation and maintains appearance under prolonged engine bay exposure. At 0.07 lbs with compact dimensions (2.05 x 1.25 x 4.05 inches), it integrates cleanly into tight engine bay layouts without sacrificing sealing integrity. AN fittings are engineered to JIC (Joint Industry Council) standards, ensuring consistent thread geometry and reliable hand-tight or wrench-tight assembly across all compatible components.

Builders and mechanics rely on ALLSTAR PERFORMANCE caps for capping unused AN ports during system testing, component swaps, and seasonal service intervals. Whether protecting fuel rails during carburetor changes, securing transmission lines during rebuild cycles, or capping pressure gauge ports in race car hydraulic systems, this cap seals against moisture and debris ingress. The fitting is a single-use item per installation, making inventory depth practical for shops maintaining multiple performance vehicles or supporting autocross and drag racing programs.

AN-10 cap fittings are foundational components in performance fuel, oil, and coolant systems. ALLSTAR PERFORMANCE is recognized across engine building and race prep communities for straightforward, reliable adapters and caps that withstand repeated assembly cycles and thermal stress without thread stripping or seal failure.
