#3 An Aluminum Tube Nut

The #3 AN Aluminum Tube Nut is a precision hydraulic and pneumatic fitting component designed for fluid power systems requiring reliable, leak-free connections. This product is essential for technicians, engineers, and equipment operators who depend on secure tubing assemblies in various applications, including industrial machinery and aircraft systems.

Manufactured by AEROQUIP, the #3 AN aluminum tube nut features durable blue anodized aluminum construction that resists corrosion while remaining lightweight. The anodized finish enhances durability and allows for visual identification in color-coded system layouts. The nut threads onto male JIC fittings with a standard pitch, creating a metal-to-metal seal when properly torqued, eliminating the need for sealant tape or additional thread compounds.

Professionals working with 3/16-inch OD tubing will benefit most from this product, as replacement and repair work often requires multiple fittings. The compact design ensures easy handling and installation in confined spaces typical of engine bays and industrial control systems.
