Tube Sleeves Alum -6AN 2pk

The Tube Sleeves Alum -6AN 2pk from ALLSTAR PERFORMANCE are essential fittings designed for high-pressure hydraulic and fuel line systems in motorsports, custom fabrication, and performance engine builds. This two-pack of aluminum tube sleeves provides secure, leak-free connections at critical junction points where reliability directly impacts engine performance and safety. Whether you're assembling a race-ready fuel system, upgrading brake lines, or routing coolant passages, these sleeves ensure professional-grade integrity in demanding applications.

Engineered for 6 AN (AN6) fittings with a 3/8-inch tube diameter, these tube sleeves feature black anodized aluminum construction that resists corrosion while maintaining precise dimensional tolerances required for vibration-resistant connections. The anodized finish protects against oxidation in engine bay environments, and the aluminum alloy provides the optimal balance of weight savings and structural rigidity. Each sleeve works in conjunction with matching fittings and ferrules to compress and seal the tubing, preventing abrasion and micro-movement that can lead to fluid weeping or catastrophic failure under pressure and thermal cycling.

Professional fabricators, drag racers, and street rodders depend on these sleeves when building fuel injection systems, nitrous oxide delivery lines, and custom cooling circuits where OEM hose is impractical. The 2pk format supplies both sleeves needed for a complete connection pair, reducing the need for separate purchases on multi-line projects. Installation is straightforward—simply slide the sleeve over the tube end, insert into the fitting body, and tighten the nut hand-tight before final torque. Compatibility extends to any 6 AN system using 3/8-inch tubing, making these sleeves a universal component in the high-performance aftermarket.
