ZeroR® AC Refrigerant | R134a Replacement | 3 Cans for AC Recharging

it's not 134a, it's some other compatible gas that uses different pressures/weights but it works. my old chevy suburban is running ice cold now. when i was pressing the gas at 2000 rpm temps went into the low 30s and idling went up to the low-mid 50s. the outside temperature is 102 right now where i live for reference. it does seem to work.

As advertised. It worked like a charm.. just hold it upside to let the freon going in.

I bought the three cans and hooked the first one up toy charging hose and for some reason it won't take the Freon from the van so I went to unhook it and the top isn't like the normal cans where you can take the can off the charging hose, because it has a valve on top these cans once you screw the van onto the hose you punch a hole in the top of the can to get the Freon out of but you can not remove the hose because the Freon will leak out no valve to stop the Freon from escaping from the can. So I'm stuck with a can of freon on my hose and to free the hose up.from the can all the Freon will leak out. I even went to the auto parts store and borrowed their hose to hook another can up to thinking my hose is clogged or something,but nope the same thing happened,no Freon into the AC system,just another can stuck onto the auto parts store hose. I don't believe these can are pressured , because if they were they would have a value on top so you can remove the hose if your system is unable to take the whole can. So do not buy this stuff I've waisted $30 on these cans so I bought more from the auto parts store and tomorrow I'll see if these can work,plus the ones from the auto parts store they have a value on top so I know I can remove the hose when done. So now I'm going to waisted a whole can of this stuff just so I can use my charging hose.

There was a problem with my order. Product is great, it was something else. What is important is this seller went above and beyond to fix it. I will be buying from them again. Excellent products and seller.

This stuff holds up very well in my ac system

This is a REPLACEMENT for R-134a refrigerant, not the actual R-134a.As the government is phasing out R-134a starting 2015.Do not mix it with R-134a refrigerant in your system, use it in an empty system.One can is 6 oz, but it's equivalent to 16 oz of R-134a.Can has puncture style opening, you must use the whole can once opened.

These are puncture cans, but they work. Just leave the gauge attached.

My son wants to charge my airconditioner in his car. He told me to order this product.
