-6an Bulkhead Fitting

The -6AN Bulkhead Fitting (SKU AFS15644) is a straight-flow fuel cell bulkhead connector engineered for high-reliability fuel system installations in motorsport, aviation, and tactical vehicle applications. This 6 AN male-to-male fitting delivers secure, leak-free connections through a jam nut and washer assembly, making it the standard choice for custom fuel cell plumbing where direct bulkhead mounting is required.

Constructed from aluminum and finished in black anodized coating, this fitting combines lightweight construction with corrosion resistance critical for long-term fuel system durability. The straight-flow design minimizes turbulence and pressure drop, supporting consistent fuel delivery across a wide range of operating conditions. The dual 6 AN connections accept standard -6 hose fittings, adapting easily into existing fuel line systems without additional adapters or converters.

This bulkhead fitting is built for users who demand precision in fuel system design: off-road enthusiasts upgrading to custom fuel cells, motorsport competitors tuning fuel delivery, and technicians assembling high-performance fuel systems where component reliability directly impacts mission success. The jam nut and washer interface provides tool-free adjustment while maintaining structural integrity under vibration and thermal cycling.

AN (Army-Navy) fittings remain the industry standard for motorsport and aviation fuel systems due to their pressure ratings and proven compatibility across OEM and aftermarket fuel cells. Proper installation requires a matching bulkhead hole and complementary -6 hose ends; verify fitment with your fuel cell documentation before purchase.
