#10 Alm Tube Nut

The #10 AN tube nut from AEROQUIP is a precision hydraulic fitting component designed for fluid power systems that demand reliable, leak-free connections. This aluminum blue anodized nut is engineered for use with 5/8-inch tubing in applications requiring 10 AN (AN10) port compatibility. Whether you're assembling high-pressure hydraulic lines for aircraft, industrial equipment, or performance automotive systems, this tube nut ensures secure, repeatable assembly and disassembly without galling or corrosion.

Constructed from lightweight aluminum alloy and finished with blue anodized protection, the #10 AN tube nut resists oxidation and corrosion in demanding environments while minimizing weight—critical in aerospace and racing applications. The 5/8-inch tube diameter specification ensures proper fit and face-seal contact, creating a fluid-tight connection when paired with compatible AN fittings and hose assemblies. The anodized coating not only enhances durability but also provides visual identification in color-coded hydraulic systems, reducing assembly errors and improving system traceability.

Professionals in aerospace maintenance, automotive restoration, and hydraulic system installation rely on AEROQUIP fittings for their consistency and performance standards. This tube nut is sold as a pair, allowing you to complete dual-line connections or keep a spare for critical systems. Compatible with all standard 10 AN tubing and fittings that meet JIC or MS specifications, installation requires only a wrench and basic mechanical knowledge—making it ideal for both OEM assembly lines and field repairs.
