Basically only the connectors have a different size in order to avoid mixing of the systems. And the cans contain the different products.
If I could get such a set with adapters for use for R12 (still allowed here in Japan) and also for R134a, then I could also do the refill on my own.
What is the price per can?
Is there anything mentioned on the cans about shipping these cans by airparcel? Or prohibited?
Have my doubts that I can get them here in Japan.
Thanks, if anybody could check that out for me.
