The REDHORSE PERFORMANCE 3AN Bulkhead Nuts Aluminum Blue (Part #924-03-1) are precision-engineered fasteners designed for fluid and pneumatic system connections in high-performance applications. This pair of blue anodized aluminum bulkhead nuts meets SAE-AN specifications for 3-size connections, providing reliable thread engagement on bulkhead fittings used in racing, aerospace, marine, and custom fabrication environments where weight reduction and corrosion resistance are critical.
The aluminum construction delivers significant weight savings compared to steel alternatives while maintaining structural integrity under pressure. Blue anodizing provides a corrosion-resistant finish that protects against oxidation in high-moisture environments and offshore applications, while also serving as a visual identifier for system assembly and maintenance. The 3AN size accommodates standard 3/16-inch hose and tubing fittings, making these nuts compatible with common fuel lines, coolant systems, brake lines, and hydraulic connections found on performance vehicles, aircraft, and watercraft.
These bulkhead nuts are essential for builders and technicians who demand consistent quality across custom plumbing installations. The two-pack quantity supports paired installations or serves as a convenient replacement set for systems requiring multiple AN connections. REDHORSE PERFORMANCE fasteners are recognized in motorsports and marine fabrication for dimensional accuracy and finish consistency, ensuring proper fitment with standard AN bulkhead fittings during assembly and service intervals.
Whether upgrading fuel system components, installing custom cooling circuits, or maintaining existing performance systems, having certified 3AN bulkhead nuts on hand prevents compatibility mismatches and reduces downtime. Compact and lightweight, this pair stores easily in tool kits and service boxes for field repairs or scheduled maintenance on racing engines, experimental aircraft, and precision hydraulic assemblies.
