Stop Leak

*For O RIngs & Seals Only 

Finally, a way to minimize the costly repairs to your auto air conditioner. Each and every year it is common to replace the lost refrigerant that leaks out over the winter months. This procedure is very costly and annoying and adds to the negligible affects to our environment with global warming.

Many leaks in the automotive air conditioner occur within the o-rings and seal areas. As o-rings and seals age, the materials begin to crack and shrink. Deterioration is the natural tendency of rubber and the heat from the engine exacerbates the deterioration.
