#12 AN W/P Fitting - Blue

The MEZIERE #12 AN W/P Fitting in blue anodized aluminum is a straight adapter designed to connect 1 inch NPT male threads to 12 AN male ports on high-performance water pump systems. Built specifically for the MEZIERE 100 Series water pumps, this fitting enables proper coolant flow configuration in custom engine cooling systems where standard port arrangements require directional adaptation.

The 12 AN male connection delivers a secure, leak-resistant interface standard in motorsports cooling applications, while the 1 inch NPT male thread accommodates OEM and aftermarket water pump outlets. Aluminum construction with blue anodized finish provides corrosion resistance and visibility for system identification during assembly and maintenance. The straight profile (versus 90-degree alternatives) minimizes installation complexity in tight engine bay environments and reduces turbulence within the coolant circuit, supporting consistent thermal management during sustained performance driving.

This fitting addresses the needs of engine builders, performance shops, and motorsports enthusiasts who rely on MEZIERE's proven water pump systems for drag racing, road course, and street performance applications. Precision cooling circuit design demands compatible fittings that match both thread standards and flow characteristics. The WP1012B fitting ensures pressure ratings and flow rates align with the 100 Series pump specifications, critical for vehicles pushing extended duty cycles where temperature stability directly impacts engine longevity and reliability.

Sold individually, this fitting integrates into larger cooling system assemblies where multiple adapters create the complete plumbing network between pump, radiator, engine block ports, and auxiliary cooling components.
