#16 AN W/P Fitting - Blue

The MEZIERE #16 AN W/P Fitting in blue anodized aluminum is a straight water pump adapter designed for high-performance cooling systems in custom and racing applications. This 1 inch NPT male to 16 AN male fitting delivers the precise flow control and reliability required in Meziere 100 Series water pumps, where proper coolant routing directly impacts engine thermal management and overall system efficiency.

Constructed from aluminum and finished in blue anodize, this adapter combines lightweight construction with corrosion resistance—critical attributes in engine bay environments where temperature cycling and coolant exposure demand durability. The straight configuration eliminates flow disruption at the connection point, while the 16 AN male port ensures compatibility with standard high-performance coolant line fittings. The NPT (National Pipe Thread) male inlet accepts plumbing connections from OEM or aftermarket water pump housings, making it a direct bolt-in solution for system integration.

This fitting serves builders and technicians upgrading cooling capacity in street rods, drag race builds, engine swaps, and high-output turbocharged platforms. Proper adapter selection prevents coolant leakage, maintains system pressure integrity, and simplifies line routing in tight engine compartments. The blue anodize finish provides visual differentiation for coolant circuit identification while protecting the aluminum base from oxidation—a practical benefit in long-term storage or marine environments where salt air exposure accelerates corrosion.
