#20 AN W/P Fitting - Blue

The #20 AN W/P Fitting - Blue from MEZIERE is a precision-engineered component designed for serious cooling system modifications and high-performance vehicle builds. This fitting is ideal for mechanics and enthusiasts who require custom coolant lines in engine bays where stock configurations are inadequate. It is particularly beneficial for those upgrading to a custom water cooling setup or installing secondary radiators.

Constructed from lightweight yet durable aluminum, the #20 AN W/P Fitting features a welded-port design that eliminates the weaknesses associated with traditional barbed or compression fittings under sustained pressure and thermal cycling. The blue anodized finish not only enhances visual identification within your system but also provides a protective oxide layer that resists corrosion and extends service life in harsh engine environments.

This fitting is essential for anyone building a custom cooling loop on LS engines, big-block strokers, or any platform requiring precision coolant routing. Its design accommodates larger-diameter hoses typical of upgraded cooling systems, ensuring minimal restriction and optimal heat transfer. With this fitting, you can achieve the reliability and performance necessary for high-demand cooling applications.
