The Fragola #3 AN Plug Black is a hex head aluminum fitting designed for high-performance automotive applications, particularly in fuel, oil, and coolant systems. This compact adapter functions as a dead-end closure for AN (Army-Navy) threaded ports, effectively preventing fluid loss and contamination in custom fuel rails and cooling circuits.
Constructed from lightweight aluminum with a black anodized finish, the #3 AN Plug is resistant to corrosion and oxidation, making it suitable for demanding underhood environments. Its hex head design allows for easy installation and removal, while the tapered AN thread form ensures a leak-free seal against standard #3 AN female ports.
This fitting is ideal for engine builders and performance enthusiasts working on custom fuel systems, turbocharged platforms, and race-spec cooling modifications. The precision manufacturing guarantees consistent thread pitch and sealing surface geometry, making it a reliable choice for various automotive applications.
