1in. Radiator Hose Fitting- Blue

The 1in. Radiator Hose Fitting in Blue by Meziere is a precision water pump adapter engineered for high-performance cooling system installations. Designed for builders and technicians working with custom or modified automotive cooling circuits, this fitting provides a critical interface between pump discharge ports and radiator hose networks. The blue anodized finish serves both functional and aesthetic purposes, offering corrosion resistance while providing visual distinction in engine bay layouts.

This straight fitting features a 12 AN male O-ring connection on one end and a 1-inch hose barb on the opposite end, enabling secure connection between Meziere water pump outlets and standard radiator hose diameters. Constructed from aluminum and anodized in vibrant blue, the fitting combines lightweight durability with superior corrosion resistance—critical properties for sustained coolant circulation under pressure and temperature cycling. The O-ring sealing interface ensures leak-free performance without requiring additional sealing tape or compounds, while the hose barb provides positive mechanical grip and secure clamp retention.

Cooling system builders, street rod fabricators, and race engine specialists rely on Meziere water pump fittings to eliminate stock cooling inefficiencies and accommodate custom plumbing configurations. This adapter works seamlessly with Meziere electric and mechanical water pump installations, as well as custom cooling loops requiring AN-standard connections. Installation requires standard hose clamps sized for 1-inch hose diameter; compatibility with both carbureted and fuel-injected platforms makes this fitting a versatile choice for vintage restorations, LS swaps, and performance engine builds.
