#6 Alum Tube Sleeves (10pk) Black

The #6 Alum Tube Sleeves (10pk) Black by FRAGOLA represent a professional-grade solution for AN hydraulic and fuel line systems where secure, leak-free connections are non-negotiable. Designed for technicians and enthusiasts working on performance vehicles, custom hot rods, aircraft systems, and precision hydraulic installations, these aluminum tube sleeves provide the mechanical grip and reliability demanded in high-pressure environments. A 10-pack quantity makes this set ideal for building complete fuel systems or maintaining existing lines without purchasing multiple individual units.

Each #6 AN tube sleeve is machined from aluminum and finished in durable black anodize, delivering corrosion resistance and a professional appearance in engine bays and fuel cells. The sleeves accommodate 3/8-inch diameter tubing and function as compression fittings—the tube slides through the sleeve while the AN fitting body compresses it to create a metal-to-metal seal that withstands vibration and thermal cycling. Black anodizing protects against oxidation in humid or salt-air environments while maintaining low weight, critical for fuel system applications where every fraction of a pound matters. The compact form factor—measuring 3.15 × 0.55 × 5.35 inches—integrates seamlessly in confined engine compartments.

Motorsport builders, shade-tree mechanics, and certified technicians rely on FRAGOLA AN fittings for consistency across fuel delivery, brake, and transmission cooler circuits. Installation is straightforward: insert the 3/8-inch tubing into the sleeve, thread the AN fitting body onto the male JIC port, and torque to specification—no special tools required beyond a wrench and the system's service manual. These sleeves are compatible with all standard -6 AN male ports and brass or aluminum AN fittings. Whether you're assembling a complete fuel injection system, restoring a vintage race car, or upgrading a street machine's hydraulic lines, this 10-pack ensures you have sleeves on hand for the entire project without rushing to reorder.
