The Tube Nut 3AN (2pk) from EARLS is an essential component for high-performance fuel and fluid line assemblies in custom automotive builds and motorsport applications. These tube nuts provide secure, leak-free connections that serious engine builders and mechanics demand, particularly for fuel delivery and return lines.
Designed to work with AN-spec (Army-Navy standard) tubing and fittings, the 3AN tube nuts are sized to fit 3AN hose and tubing assemblies, accommodating lines with a 3/16-inch inner diameter. They feature precise hex geometry and thread pitch required for AN-spec fittings, ensuring proper torque specifications and reducing the risk of cross-threading or under-tightening.
Mechanics and fabricators working on fuel system upgrades or custom engine bay layouts will appreciate the quality and consistency of EARLS fittings and fasteners. A two-pack ensures you have spares for repairs or future modifications, making these tube nuts a practical choice for any serious automotive project.
