6AN Swivel Hose Ends Blue STR

The 6AN Swivel Hose Ends Blue STR from REDHORSE PERFORMANCE is a precision-engineered straight fitting designed for custom fuel, coolant, and fluid line applications in high-performance automotive builds. Whether you're assembling a street machine, race car, or heavily modified daily driver, this swivel hose end eliminates installation stress and prevents line twist during assembly and operation. Built for professionals and enthusiasts who demand reliability under pressure, this fitting is an essential component in any serious fuel system upgrade or custom engine bay plumbing project.

Constructed from aluminum with blue and red anodized finishing, the 6AN Swivel Hose Ends Blue STR features a 360-degree swivel design that allows the hose to rotate freely without transferring torque to the fitting body or line itself. This is critical when working in tight engine bays where hose routing requires angles and bends—the swivel accommodates movement while maintaining a rock-solid connection. The straight configuration (STR) connects 6 AN hose directly to a 6 AN female port, making it ideal for fuel rails, pressure regulators, filters, and manifold blocks. Anodized aluminum provides corrosion resistance and a clean aesthetic while maintaining lightweight construction.

Mechanics and tuners favor REDHORSE swivel fittings when upgrading fuel systems on turbocharged, supercharged, or naturally aspirated performance engines where vibration and thermal cycling demand reliable plumbing. The 6AN size handles flows suitable for most carbureted and fuel-injected applications up to moderate boost levels, making it a versatile choice for street rods, muscle cars, and modified trucks. Installation is straightforward—hand-tightened with a wrench to the female port—and the swivel feature eliminates the need for secondary support clamps or alignment fittings, saving both time and frustration during complex fuel system assembly.
