A/C Pro R-1234YF AC Refrigerant Kit with Digital Gauge - 10.3 OZ

Does the job. Just a note though, when you look at the can, don't judge the product by the quantity in the can, most pure R1234yf cans are 8oz that I've been able to find, the extra is usually some stop-leak and other lubrication additives. At most, I'd add one can of refrigerant with the stop-leak and lubrication additives, beyond that I'd look to cans of pure-refrigerant without any additives for the remaining fill if one can does not fill your system. On my system, it was just barely low, showing 25psi of system pressure, only about half the can was needed to take it to 37 psi, about mid-range on the gauge display for "green". Air coming out of the vents is now about 36F-38F degrees when it's 90F degrees outside. You don't need to fill to the 55 psi limit in most cases.

Very good purchase! I was without AC in my 2018 Honda civic for MONTHS, finally decided to give this a try and I'm glad I did. My car cools better than ever now

Item worked as advertised. Charged my system and my a/c started working again and blew cold air. We'll worth it for the long road trip we had coming up.

Did a great job. Old cans were 18oz, these are only 10oz, and WAY TO EXPENSIVE! I mean really, come on!

Gauge is all over the place, cannot tell if overfilling or underfilling, this can damage my vehicle, not happy

I purchased this Freon only for it to have a faulty gauge and to not be able to use it. The store only had one in stock. Waste of money!

Okay, so my AC has a leak...I keep refilling and this is my favorite product. Wish I could find it without the gauge because I already have a few. Like that the hose is long so you can reach way back where the valve is so inconveniently placed. Gauge is awesome and easy to understand. I highly recommend this product.

very easy to use. straight forward.

this here is really a great product...highly recommend to anyone

does the job, worked just as I hoped it would
