Application
The AP13164-3 is designed for use with Rheem and Ruud water heaters as a direct OEM replacement. Heat trap nipples are critical components that prevent the natural thermosiphon effect — where hot water rises out of the tank and cold water sinks in — helping to reduce energy consumption and lower operating costs. Always verify compatibility with your specific water heater model before installation.
