-12 Aluminum Caps 10pk

The -12 Aluminum Caps 10pk (SKU: ALL 50826) is a professional-grade dust cap set designed for AN (Army-Navy) threaded fittings and hydraulic system connections. These caps protect critical fluid ports from contamination, moisture, and debris during storage, transport, and when components are disconnected. Essential for aircraft, automotive, marine, and industrial hydraulic systems, this 10-pack ensures you have protective coverage across multiple assemblies and provides spares for frequent use cycles.

Manufactured from aluminum in a natural finish, these -12 AN dust caps deliver lightweight corrosion resistance and durability in demanding environments. The aluminum construction maintains its integrity under temperature fluctuation while remaining easy to install and remove repeatedly without stripping or cross-threading. Each cap in the set is precision-engineered to seat securely on -12 AN male ports, creating an effective barrier against airborne contaminants and oxidation that could compromise hydraulic fluid quality or component longevity.

Mechanics, hydraulic technicians, and system builders benefit most from this reliable 10-pack configuration, which covers typical mission kits and emergency replacement needs. Whether you're maintaining experimental aircraft, high-performance automotive cooling systems, or industrial hydraulic machinery, having dust caps on hand prevents costly fluid contamination and downtime. The natural aluminum finish integrates seamlessly into professional installations and resists UV degradation during extended outdoor storage, making this set an indispensable consumable for any shop that services AN-threaded components.
