Bulkhead Nut #8

The Bulkhead Nut #8 from FRAGOLA is a precision aluminum fitting component engineered for high-performance hydraulic and fluid line applications. Designed for use with AN-style bulkhead fittings, this nut serves as the securing mechanism that locks bulkhead adapters firmly into bulkhead ports or reservoirs. Whether you're building a custom fuel system, brake line assembly, or coolant circuit, the Bulkhead Nut #8 provides the reliable mechanical connection required in motorsports, aerospace, and industrial hydraulic systems where leak-free performance is non-negotiable.

This #8 AN-sized nut features blue anodized aluminum construction, which delivers corrosion resistance and lightweight durability essential for systems exposed to fuel, oil, coolant, and moisture. The anodized finish prevents oxidation while maintaining the material's excellent strength-to-weight ratio—critical in racing and aerospace applications where every gram counts. The precision engineering ensures proper sealing when mated with corresponding bulkhead fittings, creating a permanent, vibration-resistant joint that withstands pressure fluctuations and thermal cycling without loosening or weeping.

Custom fabricators, race teams, and hydraulic system integrators rely on FRAGOLA Bulkhead Nut #8 components to complete leak-free assemblies in fuel cells, brake reservoirs, and fluid transfer applications. Installation requires simply threading the nut onto the bulkhead fitting body until snug—no special tools beyond a standard wrench are needed. Compatible with all AN #8 bulkhead fittings, this single nut is sold individually, allowing you to purchase exactly the quantity required for your project or maintain spare inventory for maintenance and repairs.
