AN Cap -16

The AN Cap -16 is a precision aluminum fitting designed for high-pressure fluid and fuel systems in aerospace, automotive, and industrial applications. This 16 AN (AN16) cap serves as a critical sealing component, protecting open ports and preventing contamination in hydraulic and pneumatic assemblies. Built for professionals who demand reliability under demanding conditions, the AN Cap -16 is an essential component for anyone maintaining or assembling AN-threaded systems where port protection and system integrity are non-negotiable.

Constructed from aluminum and finished in black anodizing, the AN Cap -16 offers superior corrosion resistance while maintaining a lightweight profile of just 0.13 lbs. The anodized coating provides a protective barrier against oxidation and environmental exposure, ensuring longevity in diverse operating environments. Its compact dimensions (2.1 x 1.5 x 4.05 inches) allow seamless integration into tight engine bays and system layouts. The threaded AN16 connection ensures a secure, leak-free fit when properly installed, making it suitable for systems operating at elevated pressures where standard caps would fail.

Aircraft builders, performance engine tuners, and hydraulic system technicians rely on the AN Cap -16 to seal unused ports during assembly, testing, and storage. This fitting is fully compatible with standard AN16 threaded ports found on fuel manifolds, hydraulic blocks, and pump housings. Whether you're restoring a vintage aircraft, building a custom racing engine, or maintaining industrial equipment, having quality AN caps on hand prevents fluid loss, protects internal passages from debris, and maintains system cleanliness. Installation requires only hand-tightening to a snug fit—no specialized tools required.
