    It is the right refrigerant. But the + may mean it has sealant. Sealants don't work and they can gum up the works in your system and shop recovery/charging equipment. Use 134a without sealant.

    You cannot get the wrong kind of refrigerant.

    That's fine. You won't find "the wrong" refrigerant being sold on the shelf.

    Hi the issue is about leaking pipework or units such as evaporator or condenser. the fact is when charging up a system, it should produce pressure which is read on gauges attached to the gas bottles. if the gauges read nothing the gas is escaping as it leaks away.

    Regular R-134a will work in your system. Not sure about Ultra Synthetic 134.
