#8 AN Plug

The FRAGOLA #8 AN Plug is a precision hydraulic and fluid system fitting engineered for applications requiring a reliable, sealed termination point in AN (Army-Navy) ported lines. This hex head aluminum plug delivers a dependable seal without flow-through capability, making it the standard choice for capping off unused ports in fuel systems, cooling circuits, and pressurized fluid networks across automotive, aerospace, and industrial equipment platforms.

Constructed from aluminum and finished in blue anodizing, this #8 AN plug offers corrosion resistance suitable for demanding environments while maintaining the lightweight characteristics critical in performance and racing applications. The hex head design allows secure installation and removal using standard wrenches, ensuring proper torque control during assembly. FRAGOLA fittings are manufactured to strict AN specifications, guaranteeing thread pitch and seal surface geometry that mate precisely with AN-threaded ports, eliminating guesswork in system integration and reducing the risk of leaks that could compromise system integrity or create safety hazards.

This fitting serves builders and technicians working on custom fuel systems, hydraulic brake setups, transmission coolers, and engine bay plumbing where unused AN ports must be sealed off to prevent contamination, fluid loss, or pressure drop. Whether restoring a classic performance car, building a custom off-road vehicle, or maintaining agricultural or marine equipment, the #8 AN plug provides a straightforward, codified solution. Sold individually, each plug is ready to integrate into your existing AN-component infrastructure.
