Meziere WN0040U -20AN to -16AN Polished Water Neck Fitting Adapter
Precision CNC-machined billet aluminum WN-style adapter designed for seamless integration with Meziere 300 Series water pumps and thermostat housings.
Product Overview
Engineered for high-performance motorsport cooling systems, the Meziere WN0040U adapter fitting converts a -20AN WN-style O-ring port down to a standard -16AN male hose connection. Manufactured in the USA from premium billet aluminum and finished in a mirror-like polished sheen, this adapter provides maximum fluid flow, leak-free reliability, and exceptional corrosion resistance under extreme track conditions.
Ideal for custom race builds, performance engine conversions, and upgrading remote or pump-mounted cooling circuits, the WN0040U features a straight cut O-ring seal design to ensure a dependable pressure-tight fit without thread tape or liquid sealants.
