- UNIVERSAL - ZeroR AC Refrigerant is a hydrocarbon that safely bonds with chemicals like R134a, R1234YF and R12.

- 6oz CANS - Refrigerants are compressed gasses and are measured by weight, not by liquid volume such as water. All gasses compress differently and produce a different weight. ZeroR AC Refrigerant is low weight compared to R134a, but its performance is equal to 16oz of R134a.
