#6 Tube Sleeve

The #6 Tube Sleeve from FRAGOLA is a precision AN hose fitting engineered for use in high-pressure fluid systems where secure tube connections are critical. Designed for 3/8-inch diameter tubing, this aluminum tube sleeve serves as the load-bearing compression component in AN-style connections, making it indispensable in racing fuel systems, hydraulic installations, and performance automotive applications where reliability cannot be compromised.

Manufactured from aluminum and finished in blue anodizing, the #6 Tube Sleeve provides corrosion resistance while maintaining the lightweight properties critical to performance builds. The anodized finish protects the aluminum from oxidation and chemical exposure common in fuel and hydraulic environments, while the sleeve's precision-engineered bore ensures a leak-free seal when properly installed with matching AN fittings. The 6 AN designation indicates compatibility with standard AN-6 male and female JIC adapters, a universal standard across motorsports and industrial hydraulic applications.

This tube sleeve is essential for anyone assembling or repairing fuel delivery systems, brake lines, or transmission cooler circuits on high-performance vehicles. Whether you're building a custom race car, restoring a classic, or upgrading a street machine's fuel system, proper AN tube sleeves are non-negotiable for maintaining system integrity under pressure. Installation is straightforward—the sleeve slides over the tube before final assembly with the AN fitting body, creating a permanent, high-pressure-rated connection when torqued to specification.
