Description
When you’re building a custom fluid system—whether it’s fuel, oil cooling, or brake lines—you need fittings you can trust to seal reliably under pressure. Earls’ Ano-Tuff plugs deliver precisely that: corrosion-resistant aluminum construction with a black anodized finish that handles both street and track environments. The Allen head design makes installation and maintenance straightforward, and since they come as a pair, you’ll have spares for future projects.
