John,
I read all the reviews and one notes:
By Johnathannb
This review is from: 1 Case of Enviro-Safe R134a R12 Replacement AC Refrigerant + Dye 12 Can
Having viewed the MSDS (Material Safety Data Sheet) it appears this companies refrigerants are comprised of 100% Alkanes. A little
more looking about reveals (I don't pretend to be brilliant, just curious) more commonly we know "Alkanes" as gases such as propane,
butane, methane, ethane, etc. It may be perfectly fine to use something this combustible in your home or car, but it's probably not
unfair to ask the company for a bit more clarification on why it's not potentially hazardous
I don't remember anyone on the GMCnet mentioning this product so I would give the company a call and ask it their product is the
same as Dura Cool or Frosty Cool.
Regards,
Rob M.

I just ran across Enviro-Safe on Amazon selling for $54.95 with free shipping. Can anyone verify if this is similar to Duracool?
Here are the links:

Rob M. Duracool and Frostycool are both pretty much the same mix of propane (~65%) and isobutane (~35%) (alkanes). Enviro-safe is almost certainly a nearly identical mix.

Well, I have a question about the 'do NOT pull a vacuum' which I take to mean fill the system with whatever ambient air and moisture is in it at the time. Is this stuff sufficiently hygroscopic that you won't end up freezing the expansion valve? What's the benefit of not pulling the system down?

I called Enviro-Safe this morning to ask about their product. The tech confirmed that the R134a Refrigerant with Dye is comparable with Duracool. He said that the Industrial R134a Replacement product had additives that "makes it colder". I asked about the difference between the two products and pulling a vacuum and he said you wouldn't need to for either. He said they haven't seen any issues with not pulling vacuum.
It sounds like a reasonable alternative with the free shipping from Amazon.

I'm pretty sure "don't pull a vacuum' Means don't suck out your old refrigerant.
If your system has been open, I am really really sure you need to pull a vacuum!
If for no other reason than air does not cool....

I think best practice is to pull a vacuum on your system before adding the coolant. Envirosafe (and I think Duracool) says that you don't need to pull a vacuum to use their product. I'm not sure of the the down side to skipping the vacuum, but I'm planning to vacuum my system when I replace the front seal.

Water is bad ju-ju in A/C systems no matter what the refrigerant is. Vacuum
to as close to 29.90 as you can get, leave it and see if it holds, if it
does, charge your GMC systems with 2.75 cans of Dura-Cool or similar and
enjoy the cool air.

I think there has been some misreading of this somewhere along the line. If one is just discharging a system that has R12 or r134a and you still have a small amount of residual pressure in the system then is is not necessary to use a vacuum pump. However if you are replacing a seal, a receiver / driver or s compressor or hose, or other component where the system has been exposed to the outside air and water vapor then I feel it is absolutely necessary to completely evacuate the system.
