#12 Str Ano-Tuff Hose End

The EARLS #12 Straight Ano-Tuff Hose End is a precision hydraulic and fuel line fitting engineered for demanding high-performance and industrial applications. This AN hose end adapter connects 12 AN hose to a 12 AN female port, providing a straight configuration that minimizes bending stress and maintains optimal flow characteristics in tightly packaged engine bays, custom fuel systems, and high-pressure hydraulic installations. Constructed from aluminum and finished with black anodized coating, this fitting delivers both corrosion resistance and professional appearance in competitive and street applications.

The Swivel-Seal design allows controlled hose positioning without twisting the line itself, a critical feature when managing multiple fittings in confined spaces. The 12 AN sizing (1.5-inch nominal hose ID) is specified for applications requiring substantial flow capacity—common in large-displacement fuel delivery systems, carburetor overflow lines, and hydraulic cooling circuits. Black anodized aluminum construction provides a lightweight alternative to steel while resisting oxidation in engine compartments exposed to heat cycles and moisture. The straight configuration eliminates 90-degree or 45-degree geometry, making this fitting ideal when direct port-to-hose paths are possible.

This hose end serves builders and technicians assembling custom fuel systems, supercharger intercooler lines, radiator overflow systems, and race-prepped vehicles where every millimeter of space and every degree of line routing matters. It is equally suited to marine applications, industrial hydraulic equipment, and aerospace-adjacent builds where AN standardization is required. The individual unit sale allows incremental system assembly without forcing bulk purchases.

AN fittings are the global standard for precision fluid transfer in motorsports, aviation, and military equipment. EARLS is recognized as a manufacturer of aerospace-grade hose and fitting assemblies, meaning this component meets or exceeds standards for pressure cycling, vibration resistance, and material integrity. Buyers sourcing individual AN fittings for custom fabrication typically compare specifications, material finish, and swivel design—this offering checks all three boxes with documented aluminum construction, professional anodizing, and proven Swivel-Seal engineering.
