Fitting 1-1/2 Water Pump Inlet Long

The CVR Performance Fitting 1-1/2 Water Pump Inlet Long is a precision aluminum intake adapter designed for high-flow cooling system upgrades in performance engine builds. This fitting is ideal for those transitioning from factory cooling systems to custom loops or installing aftermarket water pumps with increased displacement.

Machined from lightweight aluminum alloy, the fitting features a long inlet design that extends engagement surface for maximum structural integrity under high-pressure cooling applications. The stepped bore geometry promotes efficient coolant flow, accommodating tight engine bay layouts common in modern street machines and race platforms.

This adapter is particularly beneficial for builders upgrading to performance water pumps from manufacturers like Edelbrock, Holley, or custom fabricators running polished aluminum radiators. With a weight of just 0.37 lbs, it adds negligible weight while maintaining the precise dimensional tolerances necessary for vibration-free operation at sustained RPM.
