Liar. Nobody sells R134. We sell R134a. Viva la difference !!!
R12:

No about this false claim that R134a is ‘such a teeny molecule that it can actually pass through metals’...
Where did that nonsense come from?
R12 is dichlorodifluoromethane, and, yes, is smaller than R134a....but...
I’m pretty sure R134a is 1,1,1,2-tetrafluoroethane (you denote it as R134) rather than 1,1,2,2-tetrafluoroethane...OK, OK, picky as they are isomers and R134a probably has some ratio of both...I’m a polymer chemist, so not too familiar with R134a other than I know it’s chemical composition...
And I will agree with you about the ‘teeny molecule that can pass through metals’ comment...that’s not correct...now, heat (heat transfer) can pass through metals readily, perhaps he was referring to the cooling that occurs when R134a goes from the liquid phase to the gaseous phase? But that’s true of all refrigerants as that’s how it works...
Or, perhaps personal experience with refrigerant systems leaking? That always happens as they are not perfectly sealed systems...would be nice, but that’s generally not economically feasible...
..... well it takes a while ... but it will leak through teenier (scientific term) spaces than good old faithful R-12.
BTW, Dr. Einstein, where does it say that I am to be held to higher scientific standards than Al Gore? (Although that probably explains why "Kenny Bunk" ain't engraved on the Nobel Trophy)
