    134a refrigerant

    I recently purchased a brand new tank of R134a from a new supplier in town.
    On the box it says "For auto use only".
    Will it make a difference if I use this jug of 134a for refrigerators and other 134a applications?

    -Also it says made in China, does anyone have negative experiences with refrigerant from China?

    "for auto use only" usually means there are additives in it that are not compatible with refrigeration or AC oils.

    The only difference I know is the fitting is made for automotive A/C hoses and not the typical refrigeration hoses we use in our businesses.

    If you bought a 30lb. cylinder it's virgin refrigerant with no oil. The fitting is a ASE type fitting. Reason being they don't want you to confuse it with an R12 cylinder which has a 1/4" fitting.

    The lubricants are different and not compatible. I'm not positive but I think a 30lb tank is a 30lb tank. The small cans from walmart or pep boys have additives that will screw things up.

    Yes Sir, my understanding is (from the horse's month, DuPont back then ) there is no oil in the refrigerant. Hence Virgin. You are correct that one system use PAG and the other POE.
    The small cans can come with oil, sealer, dye, etc.

    If we look at reto blends some of those I've seen with a small percentage of proprietary ingredient.l on the MSDS.

    Our local Auto Valu bought a skid of 134a a few years back and I bought 4x 30 lb. cans at a great price. They said: “for auto use only”, but the only difference was the fitting on the tank. I had to get an ACME to Ό” adapter to hook up my manifold.

    Otherwise, it was the exact same as the DuPont 134a I usually buy from my wholesaler. The stuff from Auto-Valu was also from DuPont.

    That's where I've been getting my 134a for some time now. Typically cheaper then my supplier can sell it.

    I used the 30lb automotive 134 in reefer systems several years ago, no adverse affects.

    Many of the 30lb tanks of 134a I have been purchasing come with the adaptor
