Freeze 12

Note:  Friends. The Freeze-12 brand has been discontinued this year. Please try our more popular, more energy efficient, and less expensive brand, Enviro-Safe ES-12a and Industrial 12a. 1 lb of it is equal to 3 lbs of R-12 or 2.8 lbs of 134a. It is lighter, colder, and more efficient than R-12 or 134a and works very well in both types of systems. It is also 100% compatible with each and every aspect of both types of systems. R-12 and 134a.
