Raypak 014875F 156A Polymer Header Copper Tube Bundle Kit
The Raypak 014875F Tube Bundle Kit is a genuine replacement copper heat exchanger tube bundle for compatible Raypak 156A pool and spa heaters with polymer headers. This tube bundle is the heat-transfer component that allows pool or spa water to pass through the heater while absorbing heat from the burner system.
This replacement kit is commonly used when the original tube bundle is leaking, frozen, scaled, corroded, split, or damaged from poor water chemistry, low flow, overheating, or freeze conditions.

Important Notes
- This item is the tube bundle kit only.
- Polymer headers, complete heater, burner tray, gas valve, pressure switch, bypass assembly, sensors, control board, unions, and plumbing fittings are sold separately unless otherwise stated.
- Verify the exact Raypak heater model, BTU size, serial range, header material, and parts diagram before ordering.
- This part is for compatible 156A / 156 heater applications and is not the same as Raypak 014874F for 106A heaters.
- This tube bundle is not universal for all Raypak, Rheem, Ruud, 106A, 206A, 266A, 336A, 406A, commercial, ASME, cupro-nickel, or cast-iron header heaters.
- If the headers, bypass assembly, O-ring sealing surfaces, unitherm governor, pressure switch, or plumbing are damaged, replacing the tube bundle alone may not correct the issue.
- Heater repairs involving gas, combustion, electrical wiring, or heat exchanger replacement should be performed by a qualified pool heater technician.
Installation Notes
- Turn off electrical power to the heater before service.
- Shut off the gas supply before working inside the heater cabinet.
- Allow the heater to cool completely before removing any heat exchanger components.
- Relieve system pressure and drain the heater before removing the existing tube bundle.
- Inspect the polymer headers, bypass components, gaskets, O-ring grooves, and sealing surfaces before reassembly.
- Clean debris, scale, and old gasket material from mating surfaces before installing the new tube bundle.
- Install the included O-ring gaskets correctly and do not pinch, twist, or reuse damaged seals.
- Tighten hardware evenly according to the Raypak service instructions.
- After installation, pressure test and check for leaks before returning the heater to normal operation.
- Confirm proper water flow, gas operation, and heater safety controls before leaving the heater in service.

Maintenance Tips
- Maintain proper pool water chemistry to help reduce scale, corrosion, and premature heat exchanger failure.
- Keep water flow within the heater manufacturer’s recommended range.
- Clean filters regularly so low flow does not overheat the heater.
- Winterize the heater properly in freeze-prone conditions.
- Address heater leaks quickly to help prevent burner tray, cabinet, and electrical damage.
- Inspect bypass parts, O-rings, and headers whenever the tube bundle is serviced.
- Have repeated heater overheating, sooting, scaling, or leak issues diagnosed before replacing multiple parts.
