Mr. Stan,
I undestand.
134 is to have different fittings.
It is also to have stick on label to tell anyone that is service it what
is is in the AC system.
 You are right though, as nothing else can be put in there with these
fittings.
The other altenative things can be put in with any fitting you wish.
12 or 134 so the label is important.
Have you talked to Mr. Terry?
He told to me his head and neck is froze from new thing he put in his
AC.
I can't wait till mine gets to me
Good Evening,
Fred

Fred.
When I installed R134 in an old olds the adapter fittings has some type
of sealer/locktite or whatever on them and boy they'r like welded on.
Not chance anybody could make mistake and put freon in there again.

is to be placed on the compressor to let know the next person to service
the AC what it is.
This is not law, it is consideration
This is same even with 134a.
It should be displayed on compressor.
The ony fitting changes are for 134.
Good Evening,

Well, yeah. Personally I don't think there's any real hazard to the
driver/owner from putting a propane/isobutane refrigerant in the system.
It can be hazardous to an A/C shop that doesn't know it's there, though.
