Under the SNAP rule do you need to replace non-barrier hoses with barrier hoses when using blended refrigerants that include HCFC-22?

Yes, under the SNAP rule, non-barrier hoses must be replaced with barrier hoses when using blended refrigerants that include HCFC-22. This is to prevent the permeation of refrigerants, as barrier hoses are designed to minimize leakage and maintain system integrity. Compliance with this requirement helps ensure environmental safety and efficiency in refrigerant management.
