Adapter Fitting Bulkhead Straight 6an

The Adapter Fitting Bulkhead Straight 6AN from EARLS is a precision hydraulic and fuel line connector engineered for custom automotive, racing, and fluid power applications where reliable bulkhead mounting is critical. This straight-configuration adapter serves as a permanent panel-mount solution, allowing fluid lines to pass through compartment walls or firewall barriers while maintaining system integrity and preventing leaks. Professionals and enthusiasts rely on bulkhead fittings when space constraints or assembly geometry demands a fixed, sealed transition point rather than a traditional in-line connector.

Constructed from aluminum and finished in black anodized coating, this 6 AN male-to-male bulkhead adapter combines lightweight construction with corrosion resistance and durability in high-vibration environments. The anodized finish protects against oxidation and abrasion, extending service life in engine bays, transmission tunnels, and exposed mounting locations. EARLS' precision engineering ensures repeatable, leak-free performance under sustained pressure, critical for fuel injection systems, transmission coolers, power steering circuits, and custom hydraulic builds where even microscopic leaks compromise safety or efficiency.

This bulkhead fitting is ideal for custom fabricators, race teams, and performance shops installing aftermarket fuel systems, transmission cooling loops, or hydraulic steering kits where lines must penetrate barriers cleanly. The 6 AN port size accommodates moderate to high-flow applications typical in LS engine swaps, modern turbo platforms, and specialized cooling systems. Installation requires drilling a matching hole in your chosen bulkhead material and securing the fitting with an appropriate locknut on the reverse side—a straightforward approach that eliminates the need for complex hose routing around obstacles.
