#6 AN Plug Black

The FRAGOLA #6 AN Plug Black (480606-BL) is a hex head aluminum fitting engineered for high-pressure hydraulic and fuel line applications in motorsports, aerospace, and tactical vehicle systems. This black anodized AN plug provides a reliable, compact seal point where lines terminate or require isolation, delivering consistent performance in demanding environments where precision connections are non-negotiable.

Constructed from aluminum and finished in black anodize, this #6 AN fitting meets military specification standards for fluid power connections. The hex head design allows secure engagement with standard wrenches or fittings tools, preventing slippage during installation and maintenance. The anodized coating provides corrosion resistance in high-moisture or salt-air environments—critical for offshore, marine, and outdoor tactical applications where standard aluminum would degrade rapidly. Compact dimensions (1.2 x 1.05 x 4 inches) and minimal weight (0.02 lbs) make this plug ideal for weight-sensitive platforms such as aircraft, racing vehicles, and portable hydraulic systems.

This fitting is engineered for technicians, mechanics, and system designers working with AN-standard hydraulic or fuel networks. Whether you're assembling a custom off-road recovery winch system, restoring vintage aircraft plumbing, or maintaining tactical vehicle fluid lines, this plug seals unused AN ports cleanly and prevents contamination. It integrates directly into existing #6 AN line architectures without requiring adapters.

FRAGOLA is recognized in motorsports and aviation circles for precision aluminum fittings that withstand thermal cycling and vibration. AN (Army-Navy) specification fittings remain the standard in performance and professional applications where reliability outweighs cost—this plug represents that legacy of engineered consistency.
