Bulkhead Nut #3 Black

The Bulkhead Nut #3 Black by FRAGOLA is a crucial fastening component designed for high-performance fuel system assemblies, hydraulic lines, and precision engine modifications. This adapter fitting acts as the securing nut in bulkhead connector configurations, ensuring reliability under pressure. It is ideal for custom fuel delivery systems, remote-mounted fuel cells, and upgrades to brake or coolant infrastructure.

Engineered with precision threads and manufactured to OEM standards, FRAGOLA's bulkhead nut provides consistent clamping force across repeated assembly and disassembly cycles. The black finish offers corrosion resistance in engine bays and underbody environments where moisture and road salt pose ongoing threats to bare aluminum or steel fittings. Size #3 accommodates 1/4-inch nominal line applications, commonly used in fuel injection systems, remote filter mounts, and auxiliary cooling loops.

Mechanics and fabricators rely on FRAGOLA bulkhead nuts during EFI conversions, fuel cell installations, and turbo system plumbing, where vibration resistance and pressure integrity are critical. The compact design ensures minimal impact on weight distribution while maximizing clearance in tight engine compartments typical of modern performance builds. This product is essential for anyone looking to enhance the reliability and performance of their vehicle's fluid systems.
