Raypak RP2100 R185A/R185B ASME CI Heat Exchanger is a core heater service component used to transfer heat from the combustion side of the unit into the pool or spa water path. This item is intended for targeted repair work where matching the original part number and equipment series matters more than using a generic substitute. For best results, compare the part number 006726F, physical shape, connection points, and any model-specific notes against the component already installed on the heater or plumbing assembly.Because heat exchanger fitment is highly model-specific, this part is best used when the existing assembly, material style, and heater model match the listed Raypak application. During service, inspect nearby gaskets, fasteners, wiring, seals, brackets, or mating surfaces so the repair does not leave another worn component in place. This is especially important on older Raypak heaters, where heat, water chemistry, vibration, and corrosion can affect multiple parts around the same assembly. Supports heater water-side heat transfer and circulation Intended for the Raypak model family shown in the title Useful when replacing a leaking, scaled, cracked, or damaged exchanger Confirm header style, material, and model series before ordering Professional installation is recommended for gas heater repairs
