Raypak 336A/337A CuNi/Polymer Tube Bundle (010366F)

The Raypak 336A/337A CuNi/Polymer Tube Bundle (010366F) is a replacement tube bundle for compatible Raypak pool and spa heater applications. It helps restore the water path through the heater so heat can be transferred correctly while keeping flow and sealing surfaces aligned. 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.
