Description
If you’re running a serious fuel system, cooling loop, or brake line setup, you need fittings that won’t leak under pressure and won’t corrode after years of use. These Earls Ano-Tuff tube sleeves provide a secure, sealed connection for #4 AN tubing while the black anodized aluminum finish resists oxidation in harsh engine bay conditions. This pair gives you the reliable, leak-free connections that separate amateur builds from professional-grade work.
