R-12 replacement option
Your review: Works good as a replacement in my older Coach AC units without a bunch of hassle. Pay attention to your pressures, they will be off of what R-12 runs. Use specific RS-44 capable gauges.
Pros: Requires less to fill the system as R-12 would take. Lower running pressures. Gets really cold when charged correct.
Cons: Does not compress like R-12, real easy to lock up a compressor if you charge to fast.
