#6 Tube Sleeve 2 Pk

The #6 Tube Sleeve 2 Pk is an essential fitting component designed for AN (Army-Navy) fluid systems and high-pressure hydraulic applications. These sleeves are engineered to create secure, leak-free connections on 3/8-inch tubing, making them ideal for custom hydraulic builds, fuel systems, and brake line installations on race vehicles, off-road platforms, and precision machinery. Available as a pair, this product is built for technicians and builders who demand reliability in critical fluid-transfer environments.

Constructed from aerospace-grade aluminum and finished in vibrant blue anodizing, the #6 Tube Sleeve provides both corrosion resistance and professional aesthetics. The anodized coating protects against oxidation and wear while maintaining a clean appearance in engine bays and transmission tunnels. Each sleeve is precision-machined to AN standards, ensuring proper bite and compression on 3/8-inch tubing for consistent, dependable performance under pressure and thermal cycling. The compact 2.75 x 0.9 x 3.65-inch footprint and minimal 0.03-pound weight make installation straightforward without adding unnecessary bulk to your system.

This two-pack is perfect for custom fuel system upgrades, turbo plumbing modifications, and cooler line assemblies where AN-rated fittings are required. Compatibility spans most 3/8-inch braided hose and hard-line tubing applications, including fuel injection systems, transmission coolers, and power steering circuits. Installation requires only hand-tight assembly with a wrench—no special tools or expertise needed. Stock a pair or order multiples for complete system builds and future maintenance needs.
