According to the U.S. EPA, Hot Shot is:

50% R22
39% R124
9.5% R142b
1.5% isobutane

R22 needs barrier hoses, pure and simple. The refrigerant might otherwise fractionate and leak out the R22, leaving the remaining refrigerants behind. I'm sure they say it doesn't fractionate, but I think most of the R22 blends eventually fizz through the hoses. McKool certainly does, at 55% R22.

Freeze 12 is 80% R134a and 20% R142b.
