87-300E,

That's exactly right, we are free to have our individual opinions. It's not as if I know nothing about Freeze 12 and other blends or flammables. As jcyuhns research shows, Freeze 12 is both a blend (more than one component) and a flammable (isobutane.)

I've seen all kinds of junk used in auto air conditioners and usually without the proper fittings as required by the EPA. Have you ever read or studied for the EPA 609 certification test?

If you had, then you would know that it is illegal to use any refrigerant without installing the correct fittings. The idea is for each individual refrigerant to be protected from being mixed with another. It also offers some amount of help to the poor guys who have expensive refrigerant recovery equipment that they don't want ruined or their recovered refrigerant contaminated.

If I were to recover even the smallest volume of one of these junk refrigerants into either one of my recovery tanks, the ENTIRE TANK must then be disposed of at great expense, plus I lose the refrigerant that was in there.

There are a lot of guys with expensive equipment just trying to make a living so they can put food on the table and afford shoes for the baby like everyone else. Along comes a system with this junk, they recover into their machine because it was not correctly marked with correct fittings and they just lost several hundred dollars.

If you insist on using this junk PLEASE do everyone a favor and MARK the system as required by law and use the CORRECT fitting adapters. The service industry will thank you for it.

BTW. I am certified in automotive refrigeration by the EPA and ASE. How about yourself?

Have a great day,
