#6 Str Bulkhead Fitting Black

The #6 Str Bulkhead Fitting Black by RUSSELL is a precision hydraulic and fuel line connector designed for demanding applications where panel-mounted installations are required. This straight bulkhead fitting accommodates 6 AN (Army Navy) connections on both sides, making it essential for custom fuel systems, hydraulic brake lines, and pressurized fluid routing in race cars, performance vehicles, and industrial equipment. The bulkhead configuration allows lines to pass through a firewall or panel while maintaining a secure, leak-free seal on both sides of the mounting surface.

Constructed from aluminum and finished in black anodized coating, this fitting combines lightweight durability with corrosion resistance and professional appearance. The black anodized treatment provides superior oxidation protection for extended service life in engine bays and high-moisture environments, while the aluminum construction keeps overall system weight minimal—critical in performance and racing applications. The 6 AN male-to-male straight bulkhead design ensures proper flow direction without elbows or adapters, reducing turbulence and potential leak points in high-pressure fuel and hydraulic systems.

This fitting is ideal for fabricators, performance shops, and enthusiasts building custom fuel injection systems, turbo oil supply lines, and hydraulic brake conversions. Installation requires drilling a clean hole through the selected panel or firewall and securing the fitting with appropriate bulkhead nuts and seals—standard practice in EFI fuel system builds and aftermarket brake applications. Technicians rely on RUSSELL bulkhead fittings for their precision engineering and consistent sealing performance across temperature and pressure ranges typical of modern automotive and industrial fluid systems.
