Tube Nuts Alum -6AN 2pk

The Tube Nuts Alum -6AN 2pk from ALLSTAR PERFORMANCE is a precision fitting solution designed for fluid transfer systems in performance engines, hydraulic assemblies, and fuel delivery networks. These aluminum tube nuts are essential components for anyone building or maintaining high-performance fuel lines, brake systems, or custom fluid transfer applications. The two-pack format ensures you have backup fittings on hand for installation, repair, or system upgrades without requiring multiple purchases.

Each tube nut is engineered with black anodized aluminum construction, providing excellent corrosion resistance while maintaining a lightweight profile ideal for racing and performance builds. The -6AN sizing corresponds to 3/8-inch tubing compatibility, ensuring secure crimped or flared line connections that meet AN (Air Force-Navy) standardization specifications. The anodized finish protects against oxidation and UV damage while delivering a professional appearance on exposed installations. The compact design (3.5 x 0.8 x 4.55 inches) makes these fittings easy to handle during assembly, while the minimal weight (0.05 lbs per pair) contributes negligibly to overall system mass.

These fittings suit fabricators, engine builders, and enthusiasts who demand reliability in critical fluid systems. Installation involves sliding the tube nut onto 3/8-inch tubing with a pre-formed flare or crimp, then tightening to your system's specifications using a wrench. They are compatible with any fuel line, coolant line, or brake line assembly using -6AN specifications. Having a two-pack ensures one fitting for your primary line and one as a spare, reducing downtime during builds or emergency repairs in the shop or at the track.
