#3 Tube Sleeves (2pk)

The #3 Tube Sleeves (2pk) are essential fittings designed for fluid and pneumatic systems that rely on AN (Army-Navy) standard tubing connections. These aluminum sleeves serve a critical function in securing 3/16-inch diameter tubing to #3 AN fittings, ensuring leak-free, vibration-resistant joints in high-pressure applications. Whether you're building or maintaining a custom hydraulic system, race engine fuel line setup, or pneumatic circuit, this two-pack provides the redundancy and reliability professionals demand.

Manufactured from aluminum and finished in blue anodizing, these tube sleeves offer durability while resisting corrosion in demanding environments. The anodized coating provides both aesthetic consistency with standard AN system color-coding and functional protection against oxidation. The sleeve design compresses tightly around the tubing when the fitting is torqued, creating a mechanical lock that prevents tubing blowoff and maintains system integrity under pressure cycling and vibration. The compact form factor (0.95 x 0.6 x 2.95 inches) allows installation in tight spaces without sacrificing functionality or performance.

These sleeves are indispensable for fabricators, hot rodders, motorsports enthusiasts, and hydraulic system technicians who require OEM-quality components. They work seamlessly with #3 AN bulkhead fittings, swivel adapters, and male/female connectors commonly found in fuel injection systems, supercharger plumbing, brake lines, and transmission cooler circuits. The two-pack format ensures you have spares on hand for repairs or future projects, reducing downtime and system failures caused by improper tube retention.
