AN Cap -8

The ALLSTAR PERFORMANCE AN Cap -8 is a precision aluminum hydraulic fitting cap designed for high-pressure fluid systems in performance automotive applications. This black anodized 8 AN cap serves as a critical sealing component in fuel injection systems, cooling circuits, and custom plumbing where reliable containment of pressurized lines is essential. Built from aluminum construction with black anodized finish, it resists corrosion and blends seamlessly into modern engine bay configurations.

The 8 AN designation indicates a port size rated for SAE J518 AN-standard hose and fitting compatibility, a specification widely used in racing, hot rodding, and custom fuel system builds. AN fittings operate under pressure ratings that vary by system design, making proper cap installation critical to maintain system integrity and prevent fluid loss. The compact dimensions and lightweight construction—0.05 lbs—make this cap ideal for engine compartments where space and weight optimization matter. Black anodization provides UV protection and improves aesthetic consistency across modern performance installations.

This AN cap is essential for fabricators, engine builders, and automotive enthusiasts assembling custom fuel systems, intercooler circuits, or cooling loops. It serves as a termination point for open AN lines, preventing contamination and fluid spillage during assembly and operation. Whether capping unused ports during system testing or providing permanent line closure in a completed build, this fitting delivers the durability expected from ALLSTAR PERFORMANCE parts. Individual unit sale ensures builders have exact quantities for their specific plumbing configurations.
