Q: Can I use this tool to work on car AC port valves?
A: This tool is designed for valve ports with 1/4" or 5/16" connections, these sizes are common to home, office, commercial AC systems, refrigerator/freezer/ice maker etc. Car AC ports are different and this tool DOES NOT connect to the common car AC ports(unless the ports are 1/4" or 5/16" connections).
