Got a hole in my condenser on the car so all the freon came out so I did not have to pay to reclaim the refrigerant. I bought this kit and the cheapie air powered vacuum pump. Ordered a condenser and got my air working for $100 plus refrigerant including the tools. This worked great to put the oil charge and coolant in as well as giving me a port for the vacuum pump. Mine only came with the piercing style can adapter so if you use the other type you will need to grab an additional can adapter for the self sealing cans.
