#16 AN W/P Fitting - Red

The MEZIERE #16 AN W/P Fitting - Red (model WP1016R) is a straight water pump adapter designed for direct integration with Meziere 100 Series water pumps. This aluminum fitting bridges 1 inch NPT male threads to 16 AN male ports, providing a critical junction point for custom cooling system plumbing in performance engine builds. It is ideal for builders configuring standalone or modified cooling systems on street machines and race engines.

The red anodized finish offers both corrosion resistance and visual distinction in engine bay layouts, making it easy to trace coolant lines during maintenance or troubleshooting. Aluminum construction keeps weight minimal while delivering reliable structural integrity under typical cooling system pressures. The straight-through design eliminates flow restrictions that elbows or complex fittings introduce, allowing coolant to move efficiently from the pump outlet to auxiliary cooling components or radiator circuits.

This fitting serves builders who face plumbing challenges in engine swaps and custom cooling setups, where pump ports and aftermarket radiator or heater control fittings use different thread standards. Precise machining ensures leak-free connections when paired with appropriate hose adapters and fittings rated for your system's operating pressure. It is essential for those working with Meziere electric or mechanical water pumps.
