Male -6AN Flare Straight Hose End Fitting

The Male -6AN Flare Straight Hose End Fitting from Vibrant Performance is a critical component for any serious fuel system, coolant circuit, or hydraulic line upgrade on a modified vehicle. This fitting serves as the bridge between -6AN hose and hard-line applications, allowing you to route fuel or coolant with precision while maintaining a leak-free seal under pressure. Whether you're building a custom fuel system for a turbocharged engine, upgrading to a larger capacity fuel pump setup, or fabricating custom cooling lines for track duty, the -6AN flare straight connector gives you the flexibility to integrate hose runs with rigid tubing without compromising reliability or appearance.

This male straight hose end fitting uses a flared connection design, which creates a metal-to-metal seal that withstands high pressures and repeated thermal cycling without weeping. The -6AN designation indicates a nominal outside diameter that accommodates standard -6 AN hose, which is commonly sized for fuel system work on street and race applications up to approximately 100 psi. Vibrant Performance's engineering ensures precise thread geometry and flare cone angles that match OEM and aftermarket fuel system standards, reducing the risk of cross-threading or poor sealing during installation. The compact straight configuration minimizes space requirements in tight engine bays, making it ideal for custom fabrication where 90-degree or 45-degree elbows won't fit.

Mechanics and fabricators favor this fitting for fuel injection upgrades, fuel cell installations, and auxiliary cooling system builds where stock hard-line routing is incompatible with modifications. It integrates seamlessly with any -6AN hose and works across a broad range of fluids—gasoline, E85 ethanol blends, coolant, and synthetic oils—making it a versatile addition to your plumbing toolkit. Installation requires only a standard wrench and an understanding of proper flare fitting torque specifications (typically 15–25 ft-lbs depending on material); ensure all mating surfaces are clean and flare cones are undamaged for optimal performance on the street or strip.
