If your 266A or 267A heater is still lighting but struggling to maintain temperature, or you are seeing exchanger-side wear and internal leakage, the tube bundle is likely the real repair. Heat-transfer problems here usually show up as slow recovery, moisture in the cabinet, and a heater that feels weaker every season.
This cupro-nickel tube bundle is the internal heat-transfer assembly for compatible 266A and 267A ASME heaters. It carries water through the heated section so combustion heat can move efficiently into the system. When the bundle is scaled, damaged, or leaking, heater performance drops fast and continued use can lead to larger internal repairs.
- Slow heating and reduced overall output
- Internal exchanger leakage or moisture buildup
- Scale or wear found in the bundle during service
- Need to fix a Raypak heater with core heat-transfer failure
What this part does: It forms the internal tube bundle that transfers heat into circulating water inside the heater.
Compatibility: Designed for Raypak 266A and 267A ASME heaters. Confirm with your model number before ordering.
- Part Number: 010369F
- Type: Cupro-nickel tube bundle
- Configuration: ASME
OEM Value: A genuine Raypak bundle helps preserve the intended fit and configuration for the heater you are rebuilding. On a repair this major, correct internal assembly and material designation matter because the wrong bundle can cost you labor twice.
