The FRAGOLA Bulkhead Nut #4 Black is a precision-engineered hydraulic fitting component designed for custom fuel, oil, and brake line systems in high-performance vehicles and motorsport applications. This bulkhead nut is essential for creating secure, leak-free connections at the engine bay bulkhead, where hard lines transition into flexible hose runs.
Constructed to resist corrosion and vibration loosening, the #4 bulkhead nut is ideal for the demanding conditions of engine compartments. Its compact design measures 1.25 inches in length, 1.05 inches in width, and 4.1 inches in height, allowing for efficient fitment in tight engine bay layouts.
Mechanics and fabricators benefit from FRAGOLA's manufacturing standards, which ensure uniform thread geometry and sealing surfaces. This bulkhead nut pairs seamlessly with FRAGOLA's modular hose and fitting ecosystem, making it perfect for assembling custom fuel rails, turbo feed/return lines, and remote reservoir plumbing on various vehicle builds.
