#6 Tube Sleeves (2pk)

The #6 Tube Sleeves (2pk) by EARLS are precision-engineered aluminum fittings designed for fluid system applications requiring secure, leak-free connections on 3/8-inch tubing. These sleeves serve as critical compression components in hydraulic, fuel, and coolant lines where vibration resistance and material integrity are non-negotiable. Whether you're building a custom hot rod, restoring a vintage race engine, or maintaining industrial hydraulic systems, tube sleeves prevent tubing movement and blowouts under pressure cycling and thermal stress.

Constructed from aluminum and finished in blue anodize for corrosion resistance, the #6 Tube Sleeves feature the #6 AN (Army Navy) standard fitting configuration, ensuring compatibility with OEM and aftermarket AN-thread components. The blue anodized coating not only protects against oxidation in harsh engine bay environments but also provides color-coded identification for system organization. The two-pack format delivers a matched pair, ideal for symmetric applications or having a spare for maintenance intervals.

These sleeves pair seamlessly with #6 AN male and female fittings, carburetor fuel lines, transmission coolers, and engine oil cooling circuits. Installation is straightforward: slide the sleeve over 3/8-inch tubing and torque the fitting body to compress the sleeve, creating a permanent mechanical seal resistant to vibration-induced loosening. Professionals and enthusiasts alike depend on EARLS tube sleeves for applications where performance reliability and safety cannot be compromised.
