I am in the AC business, We use a product called "Hot Shot" to replace
R12 freon in systems. It is a " drop in " replacement. You do not need
to replace seals or oil or metering devises to use, is also is more
efficient than R12. After fixing any leaks you pull a vacuum to remove
the old R12 and refill with the same lbs of "Hot Shot"
We have used this product for 3 years with no problems. Of course you
must have an EPA license to purchase. If it leaks down you must vacuum
all out and replace total charge, usually less than 3 lbs or so.
