Yup,they do, and they ain't cheap,a little more than a tank & pump, also tanks hafta be tested and certified every 3 years ?, and if ya did have a 3rd machine for other refrigerants then ya got the disposal problem when the tank gets full, I was quoted $600, so no off the wall refrigerants here......Besides as long as the cooling system & condensor are in good enough shape to keep the high side preasure down it's been my experiance that the 134 works better than the R12 anyway.
