Have an opportunity to buy a gently used A/C recovery machine. It's an older model used for R-12 and it's variants. I read somewhere that it will not handle R134A.

So, two questions.

1. Is this true?
2. If true or not, can I at least use it to draw down a system? As in, does it have a vacuum pump in it?

I figure it would have to be equipped with ports to hook up a manifold set a least, also?

I did some digging and from what I could find they say it is OK to convert it so long as it will be a dedicated R-134 machine. Your not legally allowed to use the same machine for different refrigerants. To convert it you will have to replace any rubber seals, O-rings, and hoses to R-134 compatible barrier style hoses and seals. I know my recovery machine doesn't leak down a bit with R-12 or most any other gas, but with R-134 it will bleed down in a day or so. R-134 will seap past most any tiny leak where other gasses will not leak past.
 
Ah ok the rubber in it would be the deal. I do remember seeing the older systems 'leeching out' the 134a right through the hoses now that you mention it.

And yes, all the stuff I see/own is already retrofitted to the new refrigerant so the machine will be for this.
