#8 Str Twist-Lok Hose End

The #8 Str Twist-Lok Hose End from RUSSELL is an essential fitting component for custom fuel, coolant, and brake line systems in modified vehicles and high-performance engine builds. Whether you're fabricating a fuel rail setup, upgrading cooling circuits, or installing braided stainless steel hoses in a street rod or race engine, this straight-configuration hose end provides the secure, leak-free connection that serious automotive work demands. The Twist-Lok design ensures reliable installation and removal without specialized tools, making it ideal for both initial assembly and future maintenance on your custom automotive project.

This fitting utilizes RUSSELL's proven Twist-Lok mechanism, which creates a positive mechanical lock between the hose and the fitting body—a design choice that eliminates reliance on friction tape or thread sealant alone. The #8 sizing (typically 1/2-inch nominal diameter) accommodates mid-range flow rates suitable for fuel delivery, coolant circulation, and moderate brake system pressures in most street and strip applications. The straight-end configuration allows for direct, linear hose runs without elbows or adapters, reducing overall complexity in confined engine bay layouts and minimizing pressure drop across the system. Precision machining and quality materials ensure consistent performance across thermal cycling and vibration exposure common in modified engines.

Mechanics and enthusiasts building custom fuel systems, performance coolant circuits, or braided brake lines will appreciate the universal compatibility of this hose end across various RUSSELL-equipped applications. Installation is straightforward—simply thread the braided hose onto the fitting body using hand pressure, then snug with a wrench for a leak-proof seal without over-torquing. This fitting pairs seamlessly with AN-spec braided hose, making it a go-to choice for anyone upgrading fuel delivery on carbureted or EFI engines, retrofitting modern cooling systems into vintage builds, or fabricating custom hydraulic brake lines.
