Firstco CP81-63 Orifice Piston - 0.063 Inch

The Firstco CP81-63 is a replaceable fixed orifice piston metering device designed for residential and light commercial HVAC systems. This precision-engineered component features a 0.063-inch bore diameter that regulates refrigerant flow from the condenser to the evaporator coil.

Key Features:

• Precision 0.063-inch (63 thousandths) orifice diameter for accurate refrigerant metering
• Simple, removable design allows for easy replacement and maintenance
• Sliding piston design enables restricted flow in one direction and unrestricted bypass flow in the opposite direction for heat pump applications
• Factory-installed component compatible with standard condensing units and heat pumps
• Genuine Firstco OEM replacement part ensures proper fit and performance

As a fixed orifice metering device, this piston produces steady refrigerant flow and is a critical component for controlling refrigerant distribution in HVAC systems. Proper piston sizing based on condenser specifications is essential for optimal system performance and correct superheat readings.
