ComStar A/C Zero Leak, Permanent "Stop Leak" for A/C Systems, Instant Leak Seal, Non-Cured, Polymer Free, Eco-Friendly, Made in the USA, 4 oz (90-700)

Q: I have a 4 ton system how many OZ will needed ?

A/C Zero Leak, as well as other types, uses the amount of refrigerant in a system to determine how much stop leak should be used, not by the size (Tons) of a system. The rule of thumb is 2 to 4 lbs of refrigerant per ton. Therefore, you need to find out how much refrigerant your system operates on. The minimum refrigerant in a 4-ton system would be 8 lb and the maximum would be 16 lbs. A/C Zero Leak dosage is 1 ounce per each lb of refrigerant.

Q: Is this a 4 oz or 2 oz product? Both figures are listed on the same product page.

My bottles contained 4 oz. Not sure if there is a smaller size available.

Q: It says compatible with poe systems. is this compatible with high voltage compressors in hybrids and electric cars?

A/C Zero Leak is compatible with POE oils and A/C systems in hybrids and EVs.
