Twist-Lok Hose End #10 90 Deg Black

The Twist-Lok Hose End #10 90 Deg Black from Russell is a precision-engineered hydraulic fitting designed for custom fuel and coolant systems in high-performance automotive builds. This 90-degree adapter is built to eliminate leaks and withstand pressure cycling in demanding environments, making it ideal for fabricating fuel injection retrofits or upgrading cooling systems.

The Twist-Lok design features a threaded, twist-secure connection mechanism that locks the hose barb firmly without requiring separate clamps or ferrules, reducing assembly time and eliminating potential failure points. The #10 size designation corresponds to a fitting compatible with standard -10 AN hose, which typically has a 5/8-inch inner diameter, ensuring reliability in fuel and coolant applications.

Professional fabricators and restoration specialists benefit most from Russell Twist-Lok fittings when assembling fuel systems on carbureted engine swaps or EFI conversions. The 90-degree angle configuration is ideal for tight engine bay layouts where space is limited, allowing for efficient routing around cylinder heads and intake manifolds.
