Sporlan 168074 QC-2 Green Cartridge

The Sporlan 168074 QC-2 Green Cartridge is a precision-engineered replacement component for Type Q thermostatic expansion valves (TEVs). As a veteran technician knows, the QC-2 is a size two orifice designed to deliver reliable superheat control across various refrigeration and air conditioning applications. It is refrigerant color coded green for immediate identification on the job site. This valve cartridge service kit is compatible with multiple refrigerants, providing nominal capacities such as 1 ton for R-22 and 1/2 ton for R-404A and R-12. The package includes a matching green ID tag to ensure the capillary tubing is correctly labeled after installation. Maintaining the integrity of your HVACR expansion valve is streamlined with this drop-in replacement, which requires only a 4mm Allen wrench for field service. Designed by Parker Sporlan for conventional port valves, this cartridge ensures precise pin and port alignment to prevent hunting and ensure optimal evaporator efficiency in small-to-medium refrigeration systems.

• Precise Capacity Matching: Identified by its green color code and "QC-2" stamping to ensure correct orifice sizing during field repairs.
• Broad Refrigerant Compatibility: Engineered for use in systems running R-22, R-134a, and R-404A, supporting both high and low-temperature applications.
• Durable Construction: Features high-grade materials for maximum protection against corrosion and erosion, maintaining tight seating over time.
• Simplified Serviceability: The 168074 replacement cartridge allows for internal valve maintenance without requiring the removal of the entire valve body from the line.

• Is the 168074 identical to the QC-2 cartridge? Yes, these are different part numbering conventions for the exact same size two green cartridge.
• What tools are required for installation? A standard 4mm Allen wrench is needed to remove and secure the cartridge within the Sporlan Q valve body.
• Does this include the O-ring? Most service kits include the necessary replacement O-ring (Sporlan #791001) for a leak-proof seal during reassembly.
