R-134a R-134 R134 Air Conditioning AC Leak Stop 4oz Can

This Leak Stop is a 4 oz. can, and will work in any R-134a system. The only way refrigerant gets out of your system is if you have a leak. When adding freon to an already working system it is a good idea to use some Leak Stop. Certain states MAY restrict the sales of refrigerants to the general public. Wisconsin is the only state we are aware of at this time with such restrictions. Where there are restrictions, an EPA certificate must be presented before purchasing. Failure to do so MAY result in your order being canceled.
