ICP Metering Device .061 Chatleff Piston, 1173663
Part 1173663 is International Comfort Products' .061 Chatleff piston, a larger-bore metering device for ICP equipment that needs more refrigerant flow than the mid-range sizes. As the factory part number, it fits the ICP-built brand family: Heil, Tempstar, Comfortmaker, Arcoaire, Day & Night, KeepRite, AirQuest, EcoTemp, and GrandAire, wherever the unit is specified for a .061 piston. It's a practical choice for technicians servicing larger homes and light commercial ICP equipment, and for owners who want the exact OEM part instead of a generic substitute.
Is the .061 Piston the Right Size?
Budget Heating references the .061 for about 3.5-ton systems, but the correct piston is always the one the manufacturer specifies for the exact model. ICP assigns piston sizes by coil design, refrigerant, and position in the system, so two units with the same tonnage can call for different sizes.
Pull the existing piston and read the stamped size, then check the parts list or charging chart for your model number. When both point to .061, the 1173663 restores the original metering. Larger ICP equipment may call for the .065 or .070 instead.
Ideal for: Technicians and homeowners replacing a .061 piston in larger ICP-built Heil, Tempstar, Comfortmaker, Arcoaire, Day & Night, KeepRite, AirQuest, EcoTemp, or GrandAire systems.
Need a larger bore? Step up to the ICP .065 Metering Piston, 1173873, or step down to the ICP .052 Metering Piston, 1174060.
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 size is the ICP 1173663 piston?
Part 1173663 is a .061 Chatleff metering piston, per ICP's part description.
Can two 3.5-ton ICP units use different piston sizes?
Yes. ICP sizes pistons by the specific coil and system design, so always confirm the size for your exact model rather than relying on tonnage.
Does the 1173663 fit KeepRite equipment sold in Canada?
KeepRite is an ICP brand. When a KeepRite unit's parts list specifies a .061 piston, part 1173663 is the OEM match.
Is a .061 piston interchangeable with a .065?
No. Each bore meters a different amount of refrigerant. Use only the size your equipment specifies.
Is this piston sold individually or in a pack?
This listing is for a single piston. Use the quantity selector if your unit needs more than one.
What other parts should I have on hand for a piston replacement?
Techs commonly have a replacement filter drier, refrigerant, and any seals the unit's service instructions call for. Follow the manufacturer's procedure for your model.
