#12 AN Plug Black

The FRAGOLA #12 AN Plug Black is a hex head aluminum fitting designed to seal and cap AN-sized hydraulic or pneumatic lines in high-performance automotive, marine, and industrial applications. This black anodized plug delivers reliable line termination in systems ranging from custom fuel systems to transmission coolers and brake circuits, where precision thread engagement and corrosion resistance are essential.

Manufactured from aluminum and finished with black anodized coating, this fitting resists oxidation and corrosive environments while maintaining a professional appearance. The #12 AN size (0.75-inch diameter) accepts standard AN-size hose or tubing, and the hex head design accommodates standard wrench sizes for quick installation and removal. Weighing just 0.08 lbs, the fitting's compact 1.5 x 1.5 x 1.5-inch footprint makes it suitable for tight engine bays and confined spaces where space is at a premium.

This plug is ideal for builders and technicians who need to cap off unused AN ports during system assembly, testing, or modifications. Whether you're protecting a line from contamination during assembly, isolating a circuit during troubleshooting, or creating a permanent dead-end connection, this fitting provides a sealed, leak-free solution. The black anodized finish integrates seamlessly into custom engine bays and fuel system installations where appearance matters alongside function.

FRAGOLA fittings are recognized in the automotive performance market for precision machining and reliable thread sealing. Each plug is sold individually, allowing you to stock exactly the configurations you need without waste or excess inventory.
