Endura Tube Sleeve #6

The Endura Tube Sleeve #6 is a precision hydraulic and pneumatic fitting component engineered for systems requiring reliable fluid transfer at the 6 AN (AN6) standard. Designed for technicians, mechanics, and system integrators who demand durability in high-pressure applications, this nickel-anodized aluminum sleeve pairs with 3/8-inch tubing to create a secure, leak-resistant connection. Whether you're assembling fuel systems, brake lines, or custom hydraulic setups, the Endura Tube Sleeve #6 delivers consistent performance across automotive, aerospace, and industrial applications.

This fitting sleeve is constructed from aluminum and finished with nickel anodizing—a surface treatment that resists corrosion, oxidation, and wear while maintaining a professional appearance. The nickel-anodized finish ensures compatibility with most fluid media and extends service life in both wet and dry environments. The AN6 designation conforms to Aerospace Standard (AS) sizing, guaranteeing compatibility with industry-standard hose, tubing, and adapter components. At just 0.05 lbs, the lightweight design minimizes system weight without compromising structural integrity or connection reliability.

Professionals in motorsports, custom fabrication, and fluid power systems benefit most from the Endura Tube Sleeve #6 when building modular or retrofit assemblies where precision fitment is non-negotiable. Installation pairs seamlessly with 3/8-inch OD tubing and AN6-threaded components, requiring only basic hand tools for assembly. The product ships as a pair, allowing technicians to outfit dual-line systems or maintain spares for maintenance cycles. For those seeking upgrade or replacement sleeves that meet aerospace standards at practical pricing, this Russell offering represents a dependable choice for applications demanding long-term reliability.
