Swivel Coupling Fitting 10an Female Straight

The EARLS Swivel Coupling Fitting 10AN Female Straight (SKU: EARAT915110ERL) is a precision hydraulic adapter designed for high-performance fuel, coolant, and brake line applications where reliable connections are essential. This straight-configuration coupling enables seamless integration between two 10 AN female swivel ports, making it ideal for custom fuel systems, engine bay routing, and motorsport builds where space and accuracy matter.

Constructed from lightweight aluminum with a black anodized finish, this fitting resists corrosion while maintaining the durability required in underhood environments. The swivel design on both ports allows for precise angular alignment during installation, reducing stress on mating hose barbs and threaded connections. The 10 AN sizing corresponds to a 5/8-inch hose ID, which is the industry standard for mid-range fuel and coolant circuits, balancing flow capacity with compact packaging.

This fitting is compatible with all standard 10 AN hose assemblies, adapters, and manifold ports, making it a versatile choice for fuel system designers and restoration shops. Whether you're plumbing a race engine, upgrading your street car's fuel delivery, or assembling hydraulic brake circuits, this fitting provides the secure, leak-free junction that professional technicians and enthusiasts demand.
