Description

A quality cap fitting is essential for any pressurized fuel or fluid system—it seals off open AN ports to prevent contamination, fluid loss, and potential safety hazards during operation or storage. This #4 AN cap delivers the precision fit and durability expected in professional racing setups, whether you’re assembling a fuel system from scratch or replacing worn fittings. Black anodized aluminum construction resists corrosion while maintaining a clean, finished appearance in your engine bay.
