ZeroR MaxDry contains a dehydrating agent that converts system moisture into oil.
We recommend the use of Max Dry before the use of ZeroR Max Seal to ensure all moisture has been removed from the air conditioning system.
The 4 ounce aerosol can contains enough Max Dry to work in 3 or 4lb a/c systems.
Max Dry is perfect for the single use and may be used in most a/c systems such as R12, R134a, R22, and R502.
The 4 ounce aerosol can connects to regular system with a 134a tap
