Envirosafe refrigerant

Enviro-safe is selling R600a. More commonly known as iso-butane. Butane, you know, the stuff they put in cigar lighters. Its a hydrocarbon, a fuel, its flammable.

True, it makes a great refrigerant, but the SAE thought it best to avoid using flammable refrigerants, because the refrigeration system cycles through the engine compartment AND the passenger compartment. A leak in either area could be disastrous.

Not to mention, in a front end, or in the case of the Pantera a rear end collsion, the first thing to get hit and start leaking is the a/c cond. Butane is not something you want leaking out especially during a accident. Unfortantly I'm seeing more and more a/c systems charged with it. In fact my recycler machine has a warning sensor to protect against contamination of butane. I'd pass on it.

You might want to try Freeze 12. It works great so far!

Do you have to have a special license to buy Freeze 12?

....................................... No license required. Some NAPA stores carry it.

Sounds like there is finally some alternatives to 134a!

I have the equipment (guages and taps) to recharge r12 systems -will it work with the freeze 12 or envirosafe, or do you have to buy their adapters?

They sell retro fit kits and recharge kits on Ebay as well as individual pieces. Works great for me!

Freeze 12 in compatible with r 12. You can top off your system with freeze 12, or use all freeze 12. R12 guages work. A can of freeze 12 looks like a can of freon.

Nothing works as well as R12. Period.

Last year I spent about $800 and had a bad hose replaced, full system evacuated and recharged with 3 1/2 pounds of R12. On a cool day, I see a steady 40 degrees coming out of the dash vents. The drive home from Vegas this year was quite pleasant.

I recently obtained my EPA section 609 R12 license online for the total cost of $15.

This allowed me to buy five 14 ounce cans of NOS R12 off eBay for $81.06, delivered to my door.

I bought a used set of R12 gauges off eBay for about $40. I need to buy a can tapper and I can keep my system charged and ready for at least a few years at no added cost.

Used,gathering dust in some corner of a garage R12 recovery machines often sell on eBay for $100-$200. Most are pick-up only due to their weight. When I find one of them close enough to home, it too will be in my garage.

Mixed refrigerant systems are persona-non-gratis at any AC shop that is aware of the mix. Service thus becomes a PITA.

134a will be phased out just as R12 was.

I'm sticking with pure, reliable, efficient and still easily available R12.

YMMV

That's all it cost?

Amazing.
