-12 Aluminum Caps 50pk

The -12 Aluminum Caps 50pk from ALLSTAR PERFORMANCE are precision-engineered dust caps designed for AN (Army Navy) -12 hydraulic and pneumatic fittings commonly found in racing, aerospace, and high-performance automotive applications. These aluminum caps protect critical connection points from contamination, moisture, and debris during storage, transport, and assembly—essential safeguards when working with fuel systems, brake lines, or custom fluid transfer lines. A 50-pack bulk quantity makes this set ideal for shops, fabricators, and enthusiasts who maintain multiple systems or prepare vehicles for competition.

Constructed from lightweight yet durable aluminum in a natural finish, the -12 Aluminum Caps feature a straightforward cap-and-seal design that threads securely onto standard -12 AN male fittings. The natural aluminum material resists corrosion under typical storage conditions and remains compatible with both gasoline and synthetic hydraulic fluids. Each cap is designed to maintain a tight seal, preventing airborne contaminants from entering hose assemblies or port connections—a critical requirement in fuel injection and pressurized brake systems where particle infiltration can compromise performance or safety.

Technicians, race teams, and custom builders rely on these caps as standard consumables when assembling or servicing -12 AN systems. Whether capping hoses during a mid-season brake line rebuild, protecting fittings on a freshly fabricated fuel rail, or securing inventory on the shelf, the 50-pack quantity reduces the need for frequent reordering. Each cap threads by hand without tools, and the compact design—measuring 6 x 2.8 x 7.85 inches per pack—stacks efficiently in toolboxes or shop drawers. Genuine ALLSTAR PERFORMANCE construction ensures compatibility with all standard -12 AN male fittings across domestic and foreign platforms.
