I need a reputable source and the hose/gauge to do the fill.

Many suggestions?

If there may be air in the can, vent the gas and recheck pressure: If the pressure dropped, there was air. When the pressure is stable after venting, look at the chart.


My experience has been that thieves were marketing R22 as R12 in the South Bay area of SoCal about 10 years ago. R22 is about 30lbs higher at room temperature. Was pretty easy to verify.

Someone here must must have dealt with this before and had a favorable transaction with a vendor or source. I'm not looking to hunt on eBay if someone here has a better source.
