    They sure do. No such thing as a leak proof system. It's just a question of how much and how fast.

    409A for 12, and 408a for 502 work fine for me. Just depends on application.

    R-401A runs a little lower head/hot gas temp so I like it a little better than R-409A. Both work fine though. No need to change TXV. I use 100% alkylbenzene oil. MP39 is claimed to work just fine with mineral oil (IIRC).

    Do refrigeration techs normally carry a refrigerant identifier as a part of their arsenal?

    It was common in MVAC shops to keep the shops R12 from getting dirty from all kinds of creative mixtures people put in their car AC.

    Are you talking about the TIF machine that Snap On was selling?

    If you're using it with elastomers and hoses not meant for 134a, then this is hardly a surprise.
