Raypak 014933F Tube Bundle Kit – 406A Polymer Cupronickel
If your Raypak heater is running but not transferring heat effectively, or you’re seeing internal leakage or scaling inside the exchanger area, the tube bundle is often the root cause. This is a direct fix when a Raypak heater is not working at full output due to internal heat transfer failure.
This tube bundle kit is the internal assembly that carries water through the heated section of the heater in Model 406A polymer cupronickel configurations. When it becomes restricted, corroded, or compromised, the heater can still fire but will struggle to deliver usable heat. Replacing it restores the core heat transfer path and overall performance.
- Heater fires but water temperature barely increases
- Internal leaks or moisture buildup inside the cabinet
- Scale or corrosion inside the exchanger during inspection
- Raypak heater troubleshooting points to exchanger inefficiency
What this part does: It transfers combustion heat into circulating water through the internal tube bundle assembly.
Compatibility: Designed for Raypak Model 406A polymer cupronickel systems. Confirm with your model number before ordering.
- Part Number: 014933F
