ICP Metering Device .070 Chatleff Piston, 1173869
The ICP 1173869 is the .070 Chatleff metering piston, the largest bore in our ICP piston lineup and a genuine International Comfort Products part. It matches ICP-built equipment across the Heil, Tempstar, Comfortmaker, Arcoaire, Day & Night, KeepRite, AirQuest, EcoTemp, and GrandAire brands wherever the specified piston is .070. HVAC contractors, maintenance staff, and homeowners use it to restore factory metering in larger air conditioners and heat pumps, or wherever ICP's documentation calls for this size.
Is the .070 Piston the Right Size?
We reference the .070 for about 5-ton systems, but ICP's documentation shows why you should never size a piston by tonnage alone. In the parts list for ICP's PHN330 package heat pump, a 2.5-ton model, ICP specifies a .070 piston. Piston size depends on where it sits in the refrigerant circuit and on the coil it feeds.
Read the stamped size on the piston you removed and confirm it against the parts list or charging chart for your exact model. If you can't find either, send us the model and serial number before ordering.
Ideal for: Replacing a .070 piston in ICP-built Heil, Tempstar, Comfortmaker, Arcoaire, Day & Night, KeepRite, AirQuest, EcoTemp, or GrandAire equipment whose parts list or existing piston confirms the .070 size.
Need a smaller bore? Step down to the ICP .065 Metering Piston, 1173873, or explore our thermal expansion valves for TXV-equipped systems.
Tonnage references are general guidelines only. Always match the piston to the size specified by the equipment manufacturer for your exact model. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
What is the largest ICP piston Budget Heating carries?
The .070 (part 1173869) is the largest bore in our ICP piston lineup, which runs from .042 to .070.
Why would a 2.5-ton ICP unit use a .070 piston?
Piston size depends on the specific circuit and coil design. ICP's PHN330 package heat pump parts list, for example, specifies a .070. Always follow the size for your model.
Does the 1173869 fit Day & Night equipment?
Day & Night is an ICP brand. If its parts list or existing piston specifies .070, part 1173869 is the OEM match.
Is ICP owned by Carrier?
Yes. ICP is a subsidiary of Carrier. However, Carrier-branded equipment typically uses Carrier part numbers, so check your parts list before using an ICP piston in a Carrier unit.
Can I clean and reuse my old piston instead?
A damaged, worn, or deeply contaminated piston should be replaced. At this price, a new OEM part is usually the better choice than risking an incorrect bore.
Do I need a different piston for R-410A versus R-22?
Piston sizes are specified per model and refrigerant. Use the size listed for your exact unit; don't carry over a size from a different system.
