Swivel Coupling Fitting 8an Female Straight

The Swivel Coupling Fitting 8AN Female Straight by EARLS is a precision hydraulic adapter engineered for high-performance automotive fuel, coolant, and brake line applications. Designed for builders and experienced mechanics who demand reliability in modified engine bays, this straight fitting connects two 8 AN female ports with secure, leak-free performance under extreme conditions. Whether you're routing custom fuel rails, upgrading cooling systems, or fabricating custom brake lines, this swivel coupling provides the flexibility and durability that serious automotive projects require.

Constructed from aluminum and finished in black anodized coating, this fitting resists corrosion while maintaining a clean, professional appearance in visible engine compartments. The swivel design allows 360-degree rotation at both connection points, eliminating binding and simplifying installation even in tight quarters where rigid fittings would fail. The 8 AN (AN8) standard carries a nominal 1/2-inch bore diameter and handles pressures consistent with fuel injection, supercharger intercooler, and transmission cooler circuits—making this adapter equally at home in street builds and race-spec platforms. Compact dimensions (1.05 x 1 x 2.9 inches) and lightweight construction (0.07 lbs) ensure minimal footprint without sacrificing strength.

This fitting is essential for custom fuel system layouts, turbo coolant lines, and any plumbing scenario where two 8 AN female hose ends or adapters must connect in a straight configuration. Its swivel capability makes installation faster and reduces stress on adjacent fittings, preventing leaks and component damage over time. Compatible with all standard 8 AN hoses and adapters, it integrates seamlessly into EARLS brake and fuel system ecosystems. Trust this proven EARLS coupling for motorsports builds, street rods, supercharged street cars, and track-oriented vehicles where reliability is non-negotiable.
