[Vwdiesel] a/c, '82 diesel rabbit

[Sandy Cameron]

I was up the road at the local farm machinery parts place (RIES Equipment)
the other day after seeing all kinds of refrigeration stuff in their flyer.

They sell replacements for 134 and 12. Its called 12a. They also have hoses
to install it, Leak detector, leak stop, etc, and at reasonable prices. No
licence needed to purchase.

It was touted to replace either 134 o4 12 Lots of instructions and cautions.

Must be OK or it would not be sold off the shelf in the open.

It comes in a small pressure can the size of a small bug spray can, and is
marked flamamble, which tells me it is probably mostly propane with additives.

This organic refrigerant is going to get dupont out of the refrigerant business

I learned a few years ago, that it was a common thing to refill R12 systems
with propane, which works better than Dow R12 ever did. The amount carried
in the system would not be of any danger outdoors, perhaps if you dumped the
whole load in an underground garage and lit it, it might be exciting for an
instant, but it amounts to half whats in a bernzomatic torch, so must be
considered safe for domestic "idiot" use.
