Bulkhead Nut -10

The Bulkhead Nut -10 from ALLSTAR PERFORMANCE is a critical fluid-line component designed for high-performance fuel and brake system plumbing in racing and motorsports applications. This aluminum bulkhead fitting nut is engineered to secure AN-10 bulkhead fittings into firewall or panel-mounted installations, providing a reliable, sealed connection at system entry points. Whether you're building a custom fuel system, installing a remote fuel cell, or integrating hydraulic brake lines into a race car, this bulkhead nut delivers the precision fitment required for safety-critical systems.

Constructed from lightweight aluminum and finished with black anodizing, the Bulkhead Nut -10 resists corrosion while maintaining durability under vibration and thermal cycling common in high-performance environments. The -10 AN thread specification (3/4-16 UNF) ensures compatibility with standard AN-10 bulkhead fittings and port sizes used throughout professional racing and custom automotive builds. Black anodized finishing protects the aluminum from oxidation and provides a professional appearance on exposed installations, while the compact 0.03 lbs weight contributes negligibly to vehicle mass—a consideration in weight-critical racing platforms.

This bulkhead nut is essential for any fabricator, race team, or enthusiast implementing custom fuel delivery, brake line routing, or hydraulic system designs that require panel-mount access fittings. It pairs directly with AN-10 bulkhead fittings and works within systems operating at typical automotive pressures (fuel systems to 10+ PSI, brake systems to 1200+ PSI). Sold as a single nut, professional installations often require multiple units depending on system complexity. Installation requires only hand tools and ensures leak-free, vibration-resistant performance when properly torqued against a matching AN-10 bulkhead fitting body.
