Tube Nuts Alum -6AN 2pk

The Tube Nuts Alum -6AN 2pk from ALLSTAR PERFORMANCE is a precision fitting solution designed for fluid transfer systems, primarily in performance engines and hydraulic assemblies. These aluminum tube nuts are essential components for anyone building or maintaining fluid transfer applications. The two-pack format ensures you have backup fittings on hand for installation or repair.

Each tube nut features black anodized aluminum construction, providing excellent corrosion resistance while maintaining a lightweight profile ideal for various applications. 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.

These fittings are suitable for 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. The compact design and minimal weight contribute negligibly to overall system mass.
