so can i use 134a with just the fittings and as many orings as i can replace?

If you are just recharging the system will work by putting in enough to turn the suction side cold. Vacuum in needed when you have the system open to air. Envirosafe is Propane R290.
I guess if you have a leak you could find it with your nose! Static electricity or any other ignition source could be a bugger , especially if it were inside the car, Its ok as long as you are aware of what you have. It definitely is not something you could do for someone else without exposing yourself to some liability. Because of that I prefer a hybrid that doesn't ignite like Envirosafe can.

so anyone ever ordered off ebay before? ide rather use envirosafe then 134 but ide have to buy the equipment to put it in... i wonder if service shops out here are allowed to use envirosafe. the orileys guys here in cali had never heard of it before but it was easy to get in south dakota i guess

I can vouch for the Envirosafe.

I was a dumbass and didn't even bother to vacuum out the system. (Mainly because the cans of envirosafe I got said NOT to charge into a vacuum state) But even still, I am able to get pretty decent cooling. Doesn't freeze you out mind you, but that is because of my own mistakes, but does keep the inside of the car on a hot day at least comfortable, as long as you are moving.

I will say I once filled my.mustang with propane, and it was the coolest ac. Movin has very good points

they sell this synthetic stuff on amazon they shiped it to my house its a redtech r12a thing it worked for my stiva

134 has a vapor pressure of 213 PSI. Envirosafe has a vapor pressure of 109 . R12 has a vapor pressure of 195 PSI. All at 130 F . This reflects how hard the compressor works to hold the pressure high enough to turn vapor back to liquid. A 10% increase in pressure from R12 to 134 will increase wear more than 10% because heat at this point will be hotter as well.

134 has a smaller molecular structure than most other refrigerants. This means it leaks easier. When components are replaced 134 compatible rubbers need to be used. Old used components have deposits on the inside like a stain that resists 134 leakage, new parts do not, so lined hoses and special orings need to be used.

Short answer is you don't even need the fittings if you have the equipment to fit. You will need a vacuum pump to boil out humidity and to pull in the new charge. There is a long list of improvements of course but the the system will work.

Lol thanks for all the info guys it does help. Someone was trying to tell me the inner seals in the compressor would fail eventuallywith 134a. That's all I was really worried about.

It works great! It is propane.

Pine scented propane.

Yeah I use a hydrocarbon refrigerant in mine. :p

Super cheap stuff too. it's called Envirosafe.

Maybe I should explain my opinion a little more. Performance wise each gas has a boiling point and a vapor pressure point. The compressor has to pump a gas to enough pressure to convert it back to a liquid. The lower the pressure that this happens the less power required from the engine.

The other part of the equation is the boiling point. The colder the boiling point the better the AC system will cool the incoming air. This means the off cycle time can be longer to keep the evaporator fluctuating above and below freezing. Also less power from the engine.

I use this hybrid because of the above reasons partly, expense , blends with other refrigerants and works well with different AC oil types. Note the chart in the link too.

It appears pretty easy to dispose of with a match! Propane is an excellent refrigerant too. I like the hybrids with enough hydrocarbon to equal or better R 12 performance ( less power draw off the engine ) but with enough dilution that the hybrid will not burn at engine room temperatures.

If you're worried about the performance of 134 in a 12 system there's a new refrigerant out with properties much closer to 12 but without all the ozone-trashing awfulness. R-152A, also known as the stuff they use in those aerosol computer dusters.

134 works, but it works things a little harder to do it. It is also real easy to get anywhere. You can get it with all kinds of stuff added already to find leaks, seal leaks, make it colder .
