Fitting 1-1/2 Water Pump Inlet Long

The CVR Performance Fitting 1-1/2 Water Pump Inlet Long (part number 8150LCL) is a precision aluminum hose barb fitting engineered for electric water pump systems requiring reliable coolant flow management. This long-body fitting connects 1-1/2 inch hose barbs to 1-3/16 inch O-ring ports, delivering the dimensional accuracy and material integrity necessary for high-performance cooling circuits. The clear anodized aluminum construction resists corrosion while maintaining optical transparency for visual coolant level monitoring in customized cooling loops.

Dimensionally, this fitting measures 3.75 by 1.85 by 7.9 inches with a weight of 0.37 pounds, designed to integrate seamlessly into compact engine bay layouts where space optimization is critical. The barb-to-O-ring design ensures dual-sealing capability: the hose barb provides mechanical grip through internal ridging, while the O-ring creates a secondary hydraulic seal at the port interface. This redundancy minimizes coolant seepage in systems operating under sustained pressure or thermal cycling. The clear anodized finish provides superior corrosion resistance compared to bare aluminum, essential in environments where saltwater spray, moisture, or aggressive coolants circulate continuously.

This fitting addresses the specific needs of enthusiasts building custom cooling systems for high-output engines, marine applications, or off-road vehicles where OEM coolant passages prove inadequate. Mechanics and engine builders working with CVR electric water pumps rely on precision fittings like this to eliminate hot spots, reduce thermal stress on gaskets, and extend engine longevity. The long-body configuration accommodates manifold designs where standard fittings create clearance conflicts or flow path restrictions.

Aluminum fittings in this class have become industry standard for performance cooling circuits because they balance thermal conductivity with weight savings and ease of fabrication. The 1-1/2 inch to 1-3/16 inch bore ratio provides adequate flow area for electric pump output while maintaining seal integrity across typical cooling system pressures (12–18 psi for most applications). Proper hose clamp installation over the barb is essential to prevent separation under pressure spikes during engine startup or thermal load events.
