1.75in Hose Ext. W/P Fitting - Blue

The 1.75in Hose Extension with Water Pump Fitting in blue anodized aluminum is a critical coolant routing component designed for high-performance engine cooling systems. This extended straight fitting bridges distance between your water pump outlet and radiator hose, reducing stress on connections and accommodating non-standard engine bay layouts. Built for Meziere 100 Series water pumps and compatible cooling setups, this adapter is essential for custom engine builds, restoration projects, and racing applications where standard hose runs fall short or misalign.

Constructed from aluminum and finished in blue anodized coating, this fitting combines lightweight durability with corrosion resistance—critical for coolant systems exposed to moisture and temperature cycling. The design features a 1-inch NPT male thread on one end for secure pump connection and a 1.75-inch hose barb on the opposite end, ensuring a reliable seal with standard cooling hoses via clamp. The extended length minimizes fitting stress and pressure loss during peak circulation, maintaining optimal heat transfer efficiency while reducing vibration-induced leaks in high-RPM or motorsports environments.

This fitting is ideal for fabricators, engine builders, and enthusiasts installing Meziere centrifugal pumps in custom applications where hose routing requires extension or re-positioning. Technicians working on tight engine compartments benefit from the extended design, which eliminates the need for multiple fittings or complex hose bends that restrict flow. Installation requires hand-tightening the NPT male end to the pump outlet and sliding the hose barb into compatible cooling hose, secured with hose clamps—a straightforward process that ensures leak-free operation for street, strip, or track duty.
