Kits (east to obtain) with correct adapter fittings that screw onto your R19 fittings are used for this. correct way is to collect the R19 for disposal, install a new dryer tank, vacuum the system, refill with R138. If you have not worked on a/c before, be very careful when recharging. made sure your R138 gas can is connected to the LOW Pressure side of the system. You can do a Google search on recharging R19/138 systems. Mucho info,,,,,,
