Raypak 624 Tube Bundle (003164F)

Raypak 624 Tube Bundle is a replacement heater parts component intended for use when servicing compatible Raypak pool and spa heater models. This part is best used when the existing component is worn, damaged, missing, corroded, or no longer performing its role in the heater assembly. Because Raypak model families can include similar-looking parts with important differences in size, fuel type, ignition style, rating, or production range, the original part number 003164F should be checked before ordering.

This part supports heat-transfer service inside the heater water path, restoring efficient transfer of heat from the combustion chamber to the pool or spa water. Heat exchanger and tube bundle work should be matched carefully to the heater size and header configuration because small fitment differences can affect sealing, flow, and long-term performance. It is commonly ordered during major heater repairs where leaks, scaling, corrosion, or reduced heating performance point back to the water-side heat transfer assembly.
