The relationship between high-performance air conditioning and refrigeration (ACR) sealants and moisture is similar to a dysfunctional marriage. ACR leak sealants can’t live with moisture and they can’t live without moisture.

With more than 1 million sealant applications now sealing and preventing leaks in air conditioning/refrigeration systems worldwide, the odds are high most service techs will be confronted, if not already, with recovering refrigerants that have sealants in them. A common question is whether recovered refrigerant/sealant combinations will clog manifold gauges, recovery machines, etc.
