#8 ORB Straight Fitting

The #8 ORB Straight Fitting by Russell is a precision hydraulic hose adapter engineered for high-pressure fuel, oil, and coolant systems in performance and modified vehicles. This fitting serves as a critical connection point in custom fuel injection setups, turbo cooling lines, and aftermarket engine builds where reliable pressure containment is non-negotiable. Whether you're fabricating a fuel system for a street rod, turbocharger installation, or competition engine swap, this straight fitting provides the leak-proof interface your modified platform demands.

The #8 ORB Straight Fitting features an ORB (O-Ring Boss) port design that creates a metal-to-metal seal with a dynamic O-ring, eliminating the thread-seal dependency of NPT fittings and reducing the risk of system leaks under vibration and thermal cycling. Russell's engineering ensures this adapter handles sustained pressure spikes common in turbocharged and supercharged applications without weeping. The compact straight configuration minimizes flow restriction and installation footprint, critical when routing hoses through tight engine bays or custom frame rail layouts where space and plumbing geometry are tightly constrained.

Fabricators, engine builders, and DIY enthusiasts working on fuel system upgrades, EFI conversions, and high-flow cooling circuits will find this fitting indispensable for connecting Russell braided hoses and hard-line tubing. It integrates seamlessly with standard -8 hose sizes and works across gasoline, diesel, and alternative fuel platforms. Installation is straightforward: ensure the O-ring is properly seated, apply light thread sealant if necessary, and torque per Russell specifications to prevent damage to the seal surface and maintain system integrity during operation.
