The Raypak 336A/337A Copper Heat Exchanger is a replacement copper heat exchanger intended for use with compatible Raypak 336A/337A equipment. It is designed for repair situations where the original part is damaged, worn, corroded, cracked, missing, or no longer fitting as it should. This component is used for supporting heat transfer inside the heater so water can move through the heating section efficiently and reliably. Because heater and pool equipment parts are often model-specific, matching the manufacturer part number 010053F is the safest way to confirm compatibility before installation. Heat exchanger and tube bundle parts are central to heater performance, so accurate model matching is especially important before installation. This replacement is best suited for service technicians, maintenance teams, and pool owners who are restoring an existing system rather than replacing the full unit. Confirm the exact model series, material style, and part number, particularly when choosing between polymer, copper, copper/polymer, brass, cast iron, ASME, or CuNi versions. Review the equipment label, installation manual, exploded parts diagram, and any markings on the original part before purchase. Replacement copper heat exchanger for compatible Raypak 336A/337A equipment Use part number 010053F to help verify fit before ordering Helpful for repairs involving worn, damaged, corroded, or missing original components Designed to support proper alignment, service access, airflow, water flow, or cabinet protection depending on the application Recommended for installation by a qualified pool, spa, or heater service professional
