-3 Aluminum Caps 20pk

The ALLSTAR PERFORMANCE -3 Aluminum Caps 20-pack is an essential choice for engine builders, performance mechanics, and serious hot rodders who require precise finishing touches on custom fuel systems and carburetor setups. These caps fill a crucial need in high-performance applications where OEM components may not suffice, specifically for AN fittings sized to -3 specification. They provide dependable, lightweight covers that protect threads from contamination and oxidation during assembly and long-term storage.

Manufactured from aluminum, the -3 Aluminum Caps feature a lightweight construction that minimizes component mass while offering durability under thermal cycling and vibration stress typical of performance engines. The AN -3 sizing standard (3/16-inch nominal bore) is the smallest diameter in the AN fitting family, making these caps ideal for precision applications where space is limited and thread protection is critical. ALLSTAR PERFORMANCE's engineering ensures consistent fit and finish across the entire 20-pack, preventing issues such as stripped threads or leaks during installation.

Having a bulk supply of quality aluminum caps is vital for maintaining integrity across your fuel delivery system without compromising aesthetics or performance. These caps are particularly beneficial for those building street engines, race cars, or undertaking restoration projects. With their reliable design, they ensure that your fuel systems and carburetors remain protected and functional.
