Im looking for Info on Bulk R134a Cylinders (45lbs). My shop ordered 2 and didn't realize they were bulk cylinders.
Does anyone have any experience with these, and is there a way to hook them up to a machine to refill the internal tank cause I've seached everywhere and cant find anything. They have a vapor and liquid valve as well as a CGA 660 male fitting. If anyone has any info how these are used it will be much appreciated cause we cant sent them back.

We dealt with such cylinders in the chemistry lab. You'll likely need a regulator with a CGA 660 fitting. Or, if you have a regulator (like a nitrogen regulator), you should be able to unscrew the existing fitting and screw in a CGA 660 fitting.
