#16 Cap

The #16 Cap from Triple X Race Components is a precision aluminum fitting designed for high-performance hydraulic and fuel system applications in racing and performance automotive builds. This black anodized cap serves as a critical sealing component in 16 AN (JIC -16) line systems, preventing fluid loss and maintaining system integrity under demanding operating conditions. Whether you're assembling a custom race engine fuel system, coolant loop, or transmission cooler circuit, this fitting provides reliable, leak-free connections on -16 AN ports.

Manufactured from lightweight aluminum and finished with black anodize coating, the #16 Cap offers corrosion resistance and a professional appearance in engine bays and chassis applications. The anodized surface protects against oxidation while maintaining the material's weight advantage—critical in competition vehicles where every pound matters. The cap's compact design (3.05 x 1.7 x 3.45 inches) and minimal weight of 0.13 lbs make it ideal for tight spaces and weight-sensitive builds. Triple X Race Components' reputation for precision machining ensures that threads and sealing surfaces meet exacting JIC standards for vibration resistance and reliable pressure containment.

This cap is essential for fabricators, race teams, and enthusiasts building custom fuel, coolant, and hydraulic systems using AN-style fittings. It threads directly onto any 16 AN port, making it a drop-in solution for capping off unused line connections or plugging ports during system testing and troubleshooting. Installation requires no special tools—hand-tighten with a wrench to achieve a secure seal. Compatible with all standard 16 AN hose, tubing, and adapter components, the #16 Cap integrates seamlessly into complex fuel cell plumbing, radiator circuits, and transmission cooler setups.
