3/8in Tube Sleeve (2pk)

The RUSSELL 3/8in Tube Sleeve (2pk) is a precision-engineered fitting component designed for high-pressure hydraulic and pneumatic systems where secure, leak-free tube connections are essential. This two-pack solution addresses the core need for reliable tube attachment in motorsports, industrial equipment, and custom fabrication applications where vibration resistance and long-term durability directly impact safety and performance. Engineers and technicians choose tube sleeves as a cost-effective alternative to welding, offering quick installation without heat-affected zones or material compromise.

Manufactured from aluminum and finished in blue anodizing, the RUSSELL 3/8in Tube Sleeve delivers corrosion resistance and lightweight construction ideal for automotive and aerospace applications. The 6 AN (6/16 inch National) designation ensures compatibility with industry-standard dash tubing, while the aluminum body provides excellent thermal conductivity and won't degrade seals or fittings over extended service cycles. The anodized finish protects against oxidation in harsh environments, including moisture-heavy or salt-exposure conditions, maintaining structural integrity and thread security.

Professionals working on fuel systems, coolant lines, and brake applications will find this pair invaluable for repairs, upgrades, or complete system assembly. The compact dimensions and minimal 0.04 lb weight make installation straightforward without requiring special tools or expertise. Installation is accomplished by sliding the sleeve onto the tube before flaring or crimping, creating a unified assembly that resists loosening under vibration—critical for racing, off-road, and heavy-use vehicles. Each two-pack ensures you have a spare for future maintenance or parallel applications.
