The MEZIERE 12 AN Male to 1-1/4 Hose Adapter in black anodized aluminum is a straight-flow adapter fitting designed to bridge AN-standard ports to 1-1/4 inch hose barb connections. This adapter enables seamless integration between high-pressure hydraulic and fluid transfer systems commonly found in performance cooling loops, fuel systems, and transmission cooling applications where AN ports and hose barb connections must interface directly.
Built from aluminum with black anodized finish, this straight-flow design maintains consistent internal diameter throughout the fitting to minimize turbulence and pressure drop. The 12 AN male thread (1.5-inch diameter, 16 threads per inch per SAE J518 standard) mates with any component featuring standard 12 AN male ports, while the 1-1/4 inch barb accommodates hose with an inner diameter of 1-1/4 inches. The anodized finish resists corrosion in harsh underhood and marine environments, critical for applications exposed to moisture and temperature cycling. Weighing just 0.21 pounds, this single-unit adapter adds negligible mass while delivering reliable, leak-free connections in pressurized circuits.
This adapter is essential for builders and technicians transitioning between AN port standards and barbed hose configurations in custom cooling systems, fuel supply lines, and transmission cooling circuits. It serves applications requiring compact, direct-flow connections without elbow configurations, making it ideal for tight engine bays and performance builds where straight-through fittings maximize clearance and reduce installation complexity.
AN-to-hose barb adapters are industry standard in motorsports, marine, and high-performance hydraulic systems where component modularity and fluid management are paramount. The 12 AN specification handles flows typical of secondary cooling circuits and moderate-duty fuel delivery, while the straight configuration ensures compatibility with applications where 90-degree or 45-degree bends are not feasible or desirable.
