-20an Swivel Water Neck

The Peterson Fluid -20AN Swivel Water Neck is a 90-degree aluminum water outlet adapter designed for high-performance cooling systems in Chevy V8 engines. This fitting is essential for custom cooling line routing in street machines, race cars, and engine swaps where standard configurations may not fit. Its unique design offers flexibility and reliability for engine builders and automotive enthusiasts.

Constructed from lightweight aluminum and finished with a black anodized coating, this water neck provides excellent corrosion resistance against coolant and moisture. The swivel design allows for 360-degree hose orientation, making it easier to navigate tight engine bays and integrate aftermarket components without repositioning the neck itself. This feature is particularly beneficial for those upgrading cooling systems or fabricating custom coolant loops.

Engine builders, hot rodders, and restoration specialists will find this fitting invaluable for precise cooling line control. Whether installing a remote thermostat housing or modern electric fan setup, the Peterson Fluid -20AN Swivel Water Neck eliminates common plumbing conflicts. Its compatibility with standard braided stainless steel hose ensures a leak-free connection, making it a reliable choice for high-performance applications.
