Alum #10 Locknut Black

The Alum #10 Locknut Black from AEROQUIP is a precision bulkhead fitting nut engineered for high-pressure hydraulic and pneumatic systems where secure, leak-free connections are non-negotiable. Designed for AN (Army-Navy) standard 10 connections, this aluminum locknut serves professionals in aerospace, automotive, industrial hydraulics, and tactical applications who demand reliability under extreme conditions. The black anodized finish provides both corrosion resistance and professional aesthetics in demanding environments.

Manufactured from aluminum with black anodized coating, the Alum #10 Locknut Black delivers a lightweight yet durable connection component that resists oxidation and maintains dimensional stability in temperature fluctuations. The anodized finish creates a hard oxide layer that protects the aluminum substrate from corrosion while reducing galling during installation and removal cycles. This locknut's compact profile (2.35 x 1.1 x 3.7 inches) and featherweight construction (0.04 lbs) make it ideal for weight-critical applications without compromising structural integrity or sealing performance.

Technicians and system integrators who work with AN-10 bulkhead fittings will find this locknut essential for securing hose assemblies, fluid lines, and pressure connections in aircraft fuel systems, race vehicle hydraulics, and industrial equipment. Installation is straightforward—the nut threads onto matching AN-10 male fitting bulkheads and locks firmly to prevent vibration-induced loosening. Ensure compatibility with your AN-10 bulkhead fitting before ordering; this individual locknut is sold as a single unit and pairs with standard AN-10 male connectors across all pressure ratings and fluid types.
