r134a vs r12

What is the difference in the materials inside a drier/acumulator designed for r12 vs r134a? How cross compatible are they?


What are the differences in a orifice tube designed for r12 vs r134a? smaller holes? How cross compatible are they?

Thanks,

If you are wondering if you can use your old R12 system for 134a, I wouldn't do it.

R134a has a much higher operating pressure and that is why most of these components are changed during retrofit. The new components are made of stronger materials.

If you do not change components, you will have leaks.

Thanks for the reply Hootin,

I know that those components should be changed during a retrofit. I want to learn more about the differences though... the engineering behind it.

To determine that, you will probably have to get ahold of a manufacturer or specialist.

I am assuming they just thickened the wall thickness of the metal, but not completely sure.

Sorry I could not be of anymore help.

Maybe someone else in here will know more.
