Car AC R1234yf Valve Core Removal/Installation Tool and R134a Converter Adapter Set (with Valves, Case)

Car AC R1234yf Valve Core Removal/Installation Tool and R134a Converter Adapter Set combines two jobs in a single case for new-generation vehicle air conditioners using R1234yf refrigerant: replacing the valve core (Schrader) in the service port while the system is under pressure, and providing a transition between the R1234yf service port and service equipment with R134a connections.

When the ball valve on the tool body is closed, the refrigerant in the circuit does not escape while the valve core is being removed; after the new valve core has been fitted, the valve is opened and work continues. The low-pressure side is color-coded blue and the high-pressure side red.

Set Contents

• 2 × valve core removal/installation tool with valve (blue low pressure, red high pressure)
• 2 × R1234yf – R134a converter adapter (marked R1234yf on the body, blue and red)
• 1 × valve core wrench
• Spare valve core set, in a storage box
• Carrying case

Usage Notes

• Before replacing the valve core, the tool's valve is closed; it is opened after the work is finished.
• The color code is selected according to the service port: blue for low pressure, red for high pressure.
• The tool and adapter bodies are brass; the outer sleeves are color-anodized aluminum.
• A leak check at the connection point is recommended after replacing the valve core.
