1.50in Hose W/P Fitting Polished

The 1.50in Hose W/P Fitting Polished from Meziere is a precision water pump adapter engineered for builders and mechanics upgrading cooling systems on performance and modified vehicles. This straight hose fitting serves as the critical transition point between your high-flow water pump outlet and reinforced coolant hoses, making it essential for custom cooling loops, engine swaps, and competition builds where OEM components fall short. Whether you're installing a Meziere 100 Series water pump or integrating aftermarket cooling into a restomod, this polished fitting provides both functional reliability and finished aesthetics under the hood.

Constructed from aluminum and finished in polished trim, the 1.50in Hose W/P Fitting features a 1 in NPT male thread on the pump side and a 1-1/2 in hose barb outlet, enabling secure connection to large-diameter silicone or reinforced rubber hose without clamps or compression fittings. The barbed design creates a mechanical lock that resists pressure surges and vibration common in modified engines running higher coolant flow rates. Aluminum construction keeps weight minimal while offering excellent corrosion resistance—critical for street cars, show builds, and track vehicles where durability and clean appearance matter equally. The polished finish eliminates the need for additional detailing and integrates seamlessly into professional engine bays.

This fitting is ideal for enthusiasts building custom water pump installations on Meziere 100 Series pumps or comparable high-flow units in street rods, muscle cars, LS swaps, and vintage restorations. Mechanics and fabricators appreciate the standardized NPT and hose barb sizing, which works across multiple hose diameters and pump configurations. Installation requires only a wrench on the NPT side and hose clamps on the barb outlet; no special tools or adapters needed. Verify your pump's outlet thread size and hose diameter before ordering to ensure compatibility with your cooling system design.
