Bah. We've been over this before...

In order to be legal, you must first convert from CFC-12 to HC-134,
including fittings. THEN you can convert to Duracool.

As the EPA notes, it is illegal to convert any AC system from CFC-12
to Duracool. However, there is a nice gray area, where there is no
such restriction on AC systems that are using HC-134.

In order to fall into that legal gray area, you must convert to
HC-134 first. Find out how sucky HC-134 is. Then you can switch to
Duracool, and once again enjoy a nice cold AC system.
