ZeroR® AC Refrigerant | R134a Replacement | 2 6oz Cans for AC Recharging + 24" HD Can Tap Gauge

I filled it up with one cylinder. Everything worked. I haven't seen any freon leaks yet. But if you have a leak, don't try to do it all the time because in addition to coolant, oil also circulates in the system. Then don't finish your air conditioner, and the only way is to go to the specialists. P.S. The can is disposable, something left in the trash can is because the valve doesn't close the freon leak. You should wear glasses and gloves.

Easy to use

Should be Illegal, in fact it is. The can does not close after use. The supplied valve does not shut it after filling. It then vents the rest into the air or ground, or your hand. It is also not clear that its NOT an actually the same as R134. It even tries to cover that up in the photo using the tube.

I was leary because of various advertisements that worn against using this But after communicating with the manufacturer, it's totally compatible, and they provide much more detailed instructions on how to use it than you'll see online.

Product was defective and could not be used. Returned it at my cost for $15.29. Then was charged a $14 restocking fee on a defective product. Between the shipping and restocking fee got $7.80 back on $37.09 defective product. Don't buy from this vendor or this product from anyone.

The installation hose and gauge are of high quality.

Hey it’s cans of Freon, with a simple fast connection set up, no manifold, if you’re dealing with a slow leak in your system this works out fine.It all small enough that you can carry with you in the console
