Nowadays, polyol ester oils used with HFCs (which include R134a, R404a, R410a, R507, etc.) absorb moisture more easily than the mineral and alkylbenzene oils used with CFCs and HCFCs, so more precautions have to be taken to avoid moisture problems. They include proper triple evacuation and precautions to minimize the amount of air introduced when charging after triple evacuation.

If you check, R410a is _only_ for new equipment designed to use it. It is not for retrofitting.

The gauge set I use is a $45 Yellow Jacket set from ACR supply. From what I can tell, the only plastic parts are the inner lining of the hoses and parts of the gauges. It’s still the cheapest gauge set they sell, but plenty for most refrigeration and A/C (except for R410a) uses.

As for lines in the system coming apart, it has happened before. The biggest danger is soft soldered connections. [http://hvac-talk.com/vbb/showthread.php?t=121030&highlight=soft+solder](http://hvac-talk.com/vbb/showthread.php?t=121030&highlight=soft+solder)

For the little cans, the bottom is scored as a one time relief valve. For the big cans, there should be something similar next to the fitting.

Here are some safety links:

For those who don’t know how to work on A/C or are concerned about safety, just call a HVAC repair company.

So what does R410a, soft soldered connections, etc. have to do with the OPs problem; or any auto A/C problem?

Hopefully the OP has not bailed on this discussion and gone to get a tank of 410. We’ll never know if they went to the hospital or not.

OK4450… I am dumbfounded by Star and his refusal to acknowledge his lack of knowledge on automotive A/C systems. I still think he is just a troll on this board.

After this one, I’m starting to think you’re right Willey.

It’s hard to believe that someone could be off base this much; and repeatedly.
