Package unit Direct Inject HVAC leak sealer travels through the system by the refrigerant, finds the site of the leak where the atmospheric pressure causes the formula to react, and hardens, creating a seal. Any remaining sealant flows freely through the system, like oil does. The refrigerant with the sealant is handled and disposed of the same way as refrigerant that does not have sealant in it. Trusted by Commercial HVAC technicians across the globe. 1 sealant = systems up to 5 tons, so use 2 sealants=10 ton systems, and so on.
