Raypak 406A/407A CuNi Heat Exchanger (010363F)

The Raypak 406A/407A CuNi Heat Exchanger (010363F) is a replacement heat exchanger for compatible Raypak pool and spa heater applications. It supports efficient heat transfer between the burner system and the pool or spa water circuit, making it one of the most critical assemblies in the heater. This item is a practical choice when the original component is worn, corroded, heat damaged, missing, or no longer providing the correct fit during a heater repair. The model references in the product name should be used as the primary guide when matching this part to an existing heater. Because heater components can vary by model series, production version, fuel configuration, and installation setup, compare the complete part number and model callouts before ordering. For best results, inspect nearby gaskets, fasteners, panels, wiring, burner parts, and sealing surfaces during the repair so the replacement can be installed cleanly and without forcing alignment. Installation should be performed with the heater powered down and the appropriate gas, electrical, and water connections secured according to the service procedure for the unit.
