Alum #6 Locknut

The Alum #6 Locknut from AEROQUIP is a precision aluminum bulkhead fitting nut engineered for high-pressure hydraulic and pneumatic systems. Designed to secure AN-6 bulkhead fittings with reliability and durability, this locknut is essential for technicians, mechanics, and engineers who demand leak-free connections in aerospace, automotive, and industrial applications. The blue anodized finish provides corrosion resistance while maintaining excellent visibility in complex plumbing assemblies.

Manufactured from lightweight aluminum and finished with blue anodize coating, the Alum #6 Locknut delivers exceptional strength-to-weight performance critical in weight-sensitive environments. The AN-6 thread specification ensures compatibility with standard SAE/JIC bulkhead fittings, while the locknut design prevents vibration-induced loosening during operation. AEROQUIP's precision manufacturing guarantees dimensional accuracy and consistent thread engagement, reducing installation time and improving system reliability across demanding operating conditions.

This product is ideal for aircraft maintenance crews, hydraulic system installers, and OEM assembly operations requiring certified fastening solutions. The locknut pairs seamlessly with AN-6 bulkhead fittings in fuel systems, brake lines, coolant circuits, and pressurized fluid transfer applications. Sold as a pair, the Alum #6 Locknut provides economical coverage for dual-connection installations while ensuring inventory consistency and reducing downtime in high-volume service environments.
