6an Male to 3/8 Hose Barb Straight Black

The 6AN Male to 3/8 Hose Barb Straight Black adapter from REDHORSE PERFORMANCE is a precision hydraulic and fuel line fitting engineered for high-performance fuel systems, cooling circuits, and pressurized fluid transfer applications. This straight-port design eliminates unnecessary bends in tight engine compartments, making it ideal for custom automotive builds, racing platforms, and industrial equipment where space efficiency and clean routing are critical. Whether you're assembling a fuel injection system, intercooler loop, or transmission cooler setup, this adapter bridges AN (Army-Navy) compression fittings to standard hose barb connections.

Constructed from aluminum and finished in durable black anodizing, the 6AN Male to 3/8 Hose Barb Straight Black fitting resists corrosion while maintaining lightweight characteristics essential in performance applications. The 6 AN male thread (0.75-16 UNF) mates directly with female AN ports, while the 3/8-inch barb accommodates standard fuel-grade or coolant hose with secure mechanical retention. Black anodized finish not only enhances visual integration with modern engine bays but also provides superior oxidation resistance compared to bare aluminum, extending service life in both wet and dry environments. The straight configuration minimizes turbulence and pressure drop, critical for maintaining system efficiency under sustained boost or high-flow demand.

This adapter suits builders and technicians who demand OEM-equivalent quality without premium pricing—ideal for fuel system upgrades, custom cooling installations, and motorsport applications where reliability cannot be compromised. The compact 3.7 x 1.1 x 3.8-inch profile fits confined engine bays, and the straightforward hose-barb connection requires only clamp-style retention for quick assembly and leak-free operation. Installation pairs seamlessly with any 6 AN female port; simply apply appropriate thread sealant, torque to manufacturer specifications, and secure the 3/8-inch hose with stainless steel clamps for professional results.
