The #12 O-Ring to 1-3/4 inch Hose - Black fitting from Meziere is a precision water pump connector designed for high-performance cooling system integration. This straight adapter is specifically made to connect #12 AN male ports with O-ring face seals to 1-3/4 inch barbed hose connections, making it essential for custom cooling loops in racing engines and aftermarket water pump installations.
Constructed from aircraft-grade aluminum with a black anodized finish, this Meziere fitting resists corrosion while maintaining a professional appearance in engine bays. The O-ring seal design provides superior leak prevention compared to tapered thread fittings, eliminating the need for thread sealant and reducing installation time. The straight configuration minimizes flow turbulence and pressure drop, which is critical for maintaining optimal coolant velocity in performance applications.
This fitting serves enthusiasts upgrading factory cooling systems, fabricators assembling custom water pump kits, and engine builders integrating modern circulating pump designs into vintage platforms. Compatibility extends to any cooling system using #12 AN fittings, ensuring a reliable connection for various applications.
