#20 Water Outlet

The #20 water outlet from JOES RACING PRODUCTS is a precision-engineered water neck designed for serious engine builders and performance enthusiasts working with Chevy V6 and V8 powerplants. This bolt-on component replaces stock cooling system fittings with a straight, high-flow design that improves coolant circulation and reduces hot spots in the engine block. Built for both street and racing applications, this water outlet integrates seamlessly into modern cooling system upgrades and custom engine builds where stock geometry creates restrictive flow paths.

Machined from lightweight aluminum and finished in durable black anodize, the #20 water outlet features a 20 AN male port with an o-ring seal for leak-free, vibration-resistant connections. The straight design eliminates the sharp bends found in many factory water necks, allowing coolant to flow without turbulence while reducing pressure drop across the fitting. Weighing just 0.24 lbs, this component maintains minimal weight addition while delivering measurable thermal management improvements—critical when running upgraded radiators, high-flow water pumps, or tight engine bay cooling packages. The o-ring seal ensures compatibility with standard AN hose and fitting systems, a staple in custom cooling architectures.

Racers, engine builders, and hot rod fabricators choose this water outlet when designing or refreshing cooling systems for small-block and big-block Chevy engines. Installation is straightforward—bolt directly to the engine block where the original water neck sits—making it ideal for ground-up restorations, supercharger kits, and high-horsepower builds requiring optimized coolant paths. Whether you're tuning a street engine for daily reliability or preparing a competition vehicle, this JOES RACING PRODUCTS fitting delivers the flow efficiency and quality construction that separates purpose-built systems from stock compromises.
