#6 Alm Tube Sleeve

The #6 AN Tube Sleeve from AEROQUIP is a precision hydraulic and pneumatic fitting component designed for systems requiring secure, leak-free connections at 3/8-inch tube diameters. This aluminum tube sleeve pairs with AN fittings to create reliable assemblies in automotive, aerospace, and industrial applications where vibration resistance and long-term durability are critical. The pair configuration ensures you have matched components ready for dual-line installations or backup functionality.

Constructed from aluminum and finished with blue anodized coating, the #6 AN tube sleeve offers corrosion resistance and visual identification within color-coded systems. The anodized surface protects against oxidation while reducing galling during installation and removal, extending the operational life of both the sleeve and the mating fitting. At #6 AN specification, this sleeve accommodates 3/8-inch tubing and is engineered to maintain clamping force under pressure cycles and thermal stress, preventing micro-motion that leads to fitting failure.

Technicians and system integrators working with AN fluid transfer systems—including brake lines, fuel systems, and coolant circuits—rely on AEROQUIP sleeves for consistent performance across pressure ranges. The compact dimensions (2.35 x 1.05 x 3.65 inches) and minimal weight (0.03 lbs) make these sleeves ideal for weight-sensitive applications such as performance vehicles and aircraft hydraulics. Installation requires pairing with compatible AN tube nuts and body fittings; verify your system's tube diameter and pressure rating before assembly to ensure proper fit and safety.
