Permeation can be detected and will vary with refrigerant type and time of exposure
HEAVY-DUTY SERIES
STANDARD SERIES
EVACUATION
The atmosphere which has a higher pressure permeates to the lower pressure in the hose.
Permeation
Even with the advanced technology of today’s hoses, permeation through the hose compound still exists
Only the finest materials available are used to manufacture JB hoses to ensure a minimum amount of permeation (seepage or diffusion) of the refrigerant through the hose KOBRA® hoses are designed as transfer lines for all refrigerants (except ammonia), nitrogen, and refrigerant oils
When checking pressure rise, the atmosphere will permeate to the lower pressure in the hoses and the micron reading will slowly rise
CHARGING SYSTEM
Gas under pressure in the hose will permeate to the lower
pressure of the atmosphere.
