6AN Bulkhead Adapter Black Male Male

The REDHORSE PERFORMANCE 6AN Bulkhead Adapter Black Male Male (SKU RHP8832-06-2) is a precision hydraulic coupling component designed for custom fuel and coolant line routing in high-performance automotive builds. This adapter serves as a critical junction point in modified fuel delivery systems, allowing mechanics and enthusiasts to transition between AN-format hard lines and flexible hose runs without compromising system integrity or creating dead-end connections.

Constructed from aircraft-grade aluminum alloy with a black anodized finish for corrosion resistance and visual appeal, the 6AN male-to-male configuration allows two separate AN hose assemblies to connect through a single bulkhead penetration point. The 6AN sizing denotes a nominal hose inner diameter of 3/8 inch, suitable for moderate to high-volume fuel transfer and coolant circulation without excessive pressure drop. The bulkhead design permits clean panel or firewall mounting, reducing clutter in engine bays and protecting critical connections from heat soak and road debris.

This adapter is manufactured to strict tolerances, ensuring leak-free sealing when paired with proper AN fittings, crush washers, and assembly techniques that any serious automotive enthusiast would appreciate. Whether you're building a custom fuel system for a turbocharged engine, retrofitting a fuel cell into a vintage platform, or designing a complex coolant loop for extreme cooling demands, this bulkhead adapter provides the versatility needed for professional-grade plumbing work.
