Permenent "Stop Leak"

ComStar’s A/C Zero Leak is specially formulated to stop small leaks in evaporators and condensers as well as around gaskets and seals. This environmentally safe product can be used in automotive, commercial and residential A/C applications. A/C Zero Leak contains no polymer, which means no clogs and no worries! This distinct advantage, unlike competing products, ensures A/C Zero Leak will not form hard particulate when it comes in contact with moisture in a system.

A/C Zero Leak can also be used for preventive maintenance and be left in an operating system. For systems over 5 ton use appropriate ratio of approximately 1 oz per every 1 ton over the original 5 tons. As an alternative way to estimate the dosage necessary, please refer to the Product Info section below that show dosage by the amount of refrigerant charge that a system holds.
