Choose car A/C service tools by the job and refrigerant listed on the vehicle label. Recovery machines, vacuum pumps, gauges and dye do different work. A pump-and-gauge kit alone cannot recover refrigerant or establish that the equipment is approved for your vehicle.

Identify the job and refrigerant before buying
- Read the under-hood A/C label and service information. Check the named refrigerant and whether the vehicle requires dedicated equipment, oil or dye.
- Have leaks or cooling problems diagnosed before purchasing charging products. A vacuum pump evacuates a system after recovery, while a gauge set only measures or connects.
- Follow U.S. EPA requirements for motor vehicle A/C service, including proper recovery and certification for service for payment or barter. Consult a qualified shop if you cannot confirm the equipment or procedure. See EPA motor vehicle A/C servicing rules.

Frequently asked questions
Does an A/C vacuum pump recover refrigerant?
No. Use the approved recovery equipment for the refrigerant and application. Evacuation takes place after recovery.
Will the same gauge set fit every car A/C system?
No. Match the labeled refrigerant, required equipment and exact service fittings.
Can leak dye fix a refrigerant leak?
Dye is used for diagnosis when the vehicle maker permits it. Repair the leak using the approved service procedure.
