If I were you and I wanted a cheap way to refill a repaired R-134a system I would get a side-pierce clamp and Air Duster.
It will be either R-152a or R-134a.

Is that available in Europe?If I were you and I wanted a cheap way to refill a repaired R-134a system I would get a side-pierce clamp and Air Duster.

Many moons ago I bought it at MediamarktIs that available in Europe?
PAG 46. I lost a bit of refrigerant during the winter and loaded in another 6 oz can of R12A this spring. It’s been working fine this summer.What PAG weight are you using? And how long ago?
Apparently some cans have a tube down the center and for those cans the correct answer is to keep it upright. However, I’d like to see an empty can cut apart to prove that.ok, its PAG 46 you are using. that seems to agree with what I found here (also how much oil to add for each component replaced)

interesting that the redtec can says to us it to charge the system upside down, many youtubers saying dont hold it upside down
You should fill HC blends as liquids so that the mixture is right. They will fractionate otherwise, and you’ll get more of the more volatile component.ok, its PAG 46 you are using. that seems to agree with what I found here (also how much oil to add for each component replaced)

From my own experiments, pure propane doesn't work, 152a (Canned Air) did in numerous different vehicles.The pressure temperature curve of propane doesn't come close to matching that of R134a. Also the expansion valve or orifice tube won't be suited for it either.
At any rate hydrocarbon refrigerants like propane (R290) are compatible with any oil.
Odd, propane has an appropriate thermodynamic cycle and should have worked as long as it wasn't contaminated with water or something else. Check out the phase diagram for propane.From my own experiments, pure propane doesn't work, 152a (Canned Air) did in numerous different vehicles.
Ive mentioned before that propane really doesn't come close to the right pressure temperature curve for replacing R12 or R134a. Guys will argue that it works but that doesn't mean its right.From my own experiments, pure propane doesn't work, 152a (Canned Air) did in numerous different vehicles.
I suspect "12a" R134a replacements are blend of propane R290 and Butane (R600) to simulate the curve of 134a proper.
I rigged up a section of 3/4 pipe with reducers to 1/4 flare on either side as a sort of accumulator to flash off liquid going in.You should fill HC blends as liquids so that the mixture is right. They will fractionate otherwise, and you’ll get more of the more volatile component.
if you do a full can obviously this isn’t a big deal.
I know one shouldn’t put liquid in a working system, but I don’t see the work around besides to go slow, or let the charge fill the hose and then slowly let it flash into the low side….
