Raypak 010366F Tube Bundle – Models 336 and 337, Polymer Cupronickel

If your heater has started heating slowly, showing evidence of internal wear, or leaking from the exchanger section, a failing tube bundle can be the source of all three symptoms. This is one of the parts that can make a heater feel tired long before it quits completely.

This tube bundle is the internal heat transfer assembly for compatible models 336 and 337 in polymer cupronickel configuration. It carries the water through the heated section so the unit can do its job. When the bundle is scaled, damaged, or leaking, performance drops and the heater becomes less reliable under load.

  • Longer warm-up time and weak heater performance
  • Internal leaks tied to the bundle section
  • Exchanger teardown reveals worn or damaged tubing
  • Raypak replacement part needed for core heat transfer repair

What this part does: It forms the water-carrying bundle that absorbs and transfers heat inside the heater.

Compatibility: Designed for Raypak models 336 and 337, polymer cupronickel. Confirm with your model number before ordering.

  • Part Number: 010366F
  • Type: Tube bundle
  • Configuration: Polymer cupronickel

OEM Value: A genuine Raypak bundle helps match the intended internal configuration for the heater. When you are this deep into a repair, correct fit and material designation are what keep the job from becoming a second teardown.
