The EARLS Bulkhead Nut 10AN is a precision aluminum fitting designed for high-performance fuel, coolant, and brake line systems in custom automotive applications. This bulkhead nut secures hose connections at bulkhead fittings, preventing leaks under pressure while maintaining clean lines in engine bays, roll cages, and custom bracket installations. Whether you're building a race engine, restoring a classic with modern fuel injection, or fabricating a turbo kit, this component is essential for reliable hydraulic connections.
Manufactured by EARLS, a trusted name in motorsport plumbing systems, this 10AN bulkhead nut threads onto standard 10AN bulkhead fittings with consistent engagement and zero-leak performance. The aluminum construction keeps weight minimal—critical for performance builds—while the precision threading ensures repeatable torque specs across multiple installations. The compact design allows it to fit tight engine compartments without interference, and the body diameter provides adequate grip surface for proper installation torque without stripping threads or deforming the fitting.
Mechanics, fabricators, and engine builders rely on this bulkhead nut for EFI conversions, custom fuel systems, turbo plumbing, and radiator bypass circuits where pass-through connections are necessary. It pairs directly with EARLS bulkhead fittings and works across fuel, oil, and coolant applications at pressures typical in street and motorsport engines. This product is an essential component for anyone looking to enhance their vehicle's performance and reliability.
