Description
Leaking AN fittings compromise system integrity and create messy, unreliable installations. These Earls Ano-Tuff port plugs provide a robust sealing solution for unused #6 AN ports on your fuel, coolant, or oil lines—eliminating the need for temporary or makeshift closures. The black anodized aluminum construction resists corrosion while maintaining a clean, professional appearance in any engine bay.
