Bulkhead Nut -10AN

The Bulkhead Nut -10AN from VIBRANT PERFORMANCE is a critical fastening component engineered for high-performance fuel system, coolant line, and hydraulic brake applications in modified vehicles. This precision-machined nut secures bulkhead fittings to firewall-mounted fuel cells, custom engine bay plumbing, and race-specification cooling systems where vibration resistance and reliability are non-negotiable. Whether you're building a street rod, track car, or turbo-charged daily driver, a properly sized bulkhead nut prevents fitting separation and catastrophic fluid loss under load.

The -10AN designation indicates this nut accommodates -10 AN (JIC) thread fittings, the industry standard for motorsport and custom fabrication work. Manufactured to exact tolerances, it delivers consistent clamp load without over-tightening risk and resists loosening caused by engine vibration, thermal cycling, and pressure spikes common in modified applications. The compact, lightweight design (0.04 lbs) integrates seamlessly into tight engine compartment layouts while maintaining full structural integrity across repeated heat cycles and system pressure fluctuations.

Mechanics and fabricators rely on VIBRANT PERFORMANCE hardware when assembling fuel injection systems, custom radiator setups, or supercharger supply lines that demand leak-free performance. This bulkhead nut pairs with -10AN hoses, fittings, and valves across virtually all performance platforms—LS engines, small-block Chevys, Ford modular engines, and forced-induction builds. For anyone upgrading fuel delivery, cooling flow, or brake lines on a modified vehicle, stocking quality fasteners like this nut ensures professional-grade results and long-term system reliability.
