Tsk, tsk, tsk......

I assume that you used the correct Freeze 12 fittings and properly labeled the system as required by Federal law! If you did not, you are setting up a disaster for some poor guy in the future who will unknowingly recover the junk into his R12 tank which will contaminate the entire tank incurring the loss of all refrigerant in the tank, plus incurring a disposal fee. PLEASE use proper fittings and labels to prevent this disaster for some innocent tech. That poor guys is just trying to put food on the table and shoes on the baby like everybody else.
