How large of a leak will ProSeal repair?
If the leak does not empty the system within 24 hours ProSeal will typically seal the system with one can. However, two cans or more cans may be necessary if leaks persist. (This Information does NOT apply to industrial systems.)
For systems that are larger than 3 or 4 lbs please contact Enviro-Safe for technical assistance at 888-913-1110.
