3AN Bulkhead Nuts Aluminum Blue 2/pkg

The REDHORSE PERFORMANCE 3AN Bulkhead Nuts Aluminum Blue (2/pkg) are precision-engineered fittings designed for high-performance fuel, coolant, and hydraulic line assemblies in modified and race vehicles. These bulkhead nuts are essential for automotive enthusiasts and professional mechanics who require reliable connections in custom fuel systems or cooling circuits.

Machined from lightweight aluminum and anodized in a distinctive blue, the 3AN bulkhead nuts feature a 37-degree JIC flare seat that creates a leak-proof seal when mated with properly flared AN hose. The aluminum construction not only reduces overall system weight but also provides resistance to corrosion from fuel, ethanol blends, and engine bay chemicals. The hex body allows for secure installation with standard wrenches, making it easy to fit in tight engine bay spaces.

These bulkhead nuts are ideal for various applications, including fuel systems, cooling lines, and hydraulic circuits. Their compact design ensures compatibility with tight spaces where larger fittings might interfere with other components. Whether upgrading a fuel system or enhancing a cooling loop, these fittings deliver the performance and reliability needed for demanding automotive applications.
