What It Helps Address

• Expansion valve restriction or wear in the original unit
• Service replacement needs on listed Hyundai and Kia models

Installation Notes and Tips

Verify the vehicle’s refrigerant type, connection style, and model-year application before installation. This valve uses female insert O-ring connections and is not threaded, so the sealing surfaces and O-rings should be inspected carefully during service. Confirm the system is configured for the listed fitment, including the 2017 Hyundai Ioniq note for vehicles without a heat pump and built to 1/5/2017. For best results, evacuate and recharge the system according to OEM service procedures after replacement.
