6AN Male to 6AN Female 45Deg Black

The 6AN male to 6AN female 45-degree black fitting from REDHORSE PERFORMANCE is an essential component for high-performance fuel systems, oil coolers, and custom hydraulic lines in modified vehicles. This adapter serves as a directional connector that allows you to change flow direction by 45 degrees while maintaining a secure AN-threaded connection on both ends. Built for serious automotive enthusiasts who demand precision plumbing in their engine bays, this fitting bridges two 6AN hose assemblies at an angle, eliminating bulky 90-degree elbows and providing clean routing through tight spaces common in turbocharged engines and fuel-injected builds.

REDHORSE PERFORMANCE fittings are engineered from aerospace-grade aluminum with a black hard-anodized finish that resists corrosion and provides a professional appearance under the hood. The 45-degree geometry reduces pressure losses compared to 90-degree configurations while minimizing stress on hose assemblies during acceleration and braking events. The male inlet threads directly into female receiver ports (manifolds, coolers, or block fittings), while the female outlet accepts standard 6AN hose ends with JIC flare or crimp seals. This design prevents leaks in high-pressure fuel systems and oil-cooling circuits where vibration and thermal cycling demand dependable mechanical connections.

Mechanics and fabricators rely on this fitting when custom-routing fuel lines through engine bays on LS swaps, fuel system upgrades, and remote-mounted oil cooler installations. The compact 2.8-inch body fits into congested areas where larger fittings create clearance headaches, making it ideal for turbo installations and aftermarket fuel rail setups. Compatibility spans any system using 6AN (-6) hose size, including EFI conversions, racing fuel systems, and engine oil coolers on street and track vehicles. Secure the fitting with a wrench on the hex body, use thread sealant on male connections into aluminum components, and torque hose ends to manufacturer specs to ensure leak-free performance over thousands of miles.
