6AN Alum Tube Sleeve Use with 818-06 2/pkg

The 6AN Alum Tube Sleeve for use with 818-06 fittings is a precision-engineered component designed for high-performance fuel and fluid line routing in custom automotive builds and race applications. Built by REDHORSE PERFORMANCE, this aluminum tube sleeve reinforces and protects braided hose assemblies while maintaining a clean, professional appearance in engine bays and fuel system installations. Whether you're building a fuel-injected swap, upgrading a carbureted engine's fuel delivery, or constructing a custom cooling or brake line circuit, this sleeve provides structural support where lines pass through bulkheads or high-vibration areas.

Manufactured from durable aluminum, the 6AN tube sleeve reduces chafing and abrasion damage to braided hose jackets by isolating the line from sharp edges, engine block corners, and firewall penetrations. The sleeve's compact design (2.8 x 1.15 x 3.8 inches) allows discreet installation in tight engine compartment spaces without restricting access or adding bulk. This package includes two sleeves, allowing you to protect multiple hose runs or provide spares for future modifications—a practical solution when working with -6 AN hose assemblies that demand consistent sizing and reliable support throughout the fuel, coolant, or brake system.

Mechanics, fabricators, and enthusiasts standardizing on -6 AN hose fittings will find these sleeves essential for long-term durability and vibration isolation in high-performance or race-prepped vehicles. The aluminum construction resists corrosion and maintains its finish under engine heat and chemical exposure, making it ideal for street cars, track vehicles, and engine bay restorations. Compatible with all 818-06 fitting assemblies, this two-pack delivers professional-grade protection at a reasonable cost per application, ensuring your hose investments stay protected and your fuel or cooling lines maintain consistent routing alignment over thousands of miles.
