Twist-Lok Hose End #8 90 Deg Black

The Twist-Lok Hose End #8 90 Degree Black from Russell is a precision-engineered hydraulic fitting designed for high-performance fuel, oil, and coolant line applications in modified and stock vehicles alike. This 90-degree adapter serves as a critical junction point in any custom fuel system, turbo setup, or engine bay plumbing where space constraints or routing requirements demand an angled connection. Whether you're building a fuel-injected engine conversion, upgrading to larger displacement, or fabricating a competition-grade cooling system, this fitting ensures leak-free performance under pressure while maintaining the clean, race-inspired aesthetic of black anodized finishes.

Russell's Twist-Lok design employs a threaded body with reliable JIC (Joint Industry Council) internal sealing geometry, eliminating the need for separate crush washers and reducing installation complexity on the dyno or in tight engine compartments. The #8 size accommodates -8AN hose—the industry standard for fuel delivery and return circuits on engines producing 400+ horsepower—while the 90-degree geometry allows mechanics to route hoses away from heat sources, moving components, and exhaust systems without kinking or excessive bending radius violations. Black zinc-nickel plating provides corrosion resistance in salt-air environments and resists fluid staining, maintaining appearance during extended storage or outdoor projects.

This hose end suits both street and track builds where vibration isolation and pressure integrity matter: turbo fuel systems, nitrous oxide distribution blocks, remote oil filtration setups, and custom coolant bypass configurations all benefit from Russell's precision manufacturing tolerances. Installation requires only a standard wrench on the hex body; once torqued to specification against your hose barb or pump port, the fitting delivers maintenance-free operation across ambient conditions from -40°F to 250°F fluid temperature. Mechanics and fabricators rely on Russell's Twist-Lok line for repeatability—threads won't strip, seals won't weep, and routing stays clean across engine revisions and dyno pulls.
