Stop Leak for R1234yf Systems, R-1234yf Stop Leak

Worked as explained, fast delivery ...

Follow the instructions in the description, work super fast and make the a/c better than before, you have to have more gas r1234yf because you have to refill to the point 35-40 psi no more in the lower pressure port, I used on my suv since 2 months and no issues

2018 Honda kept losing the expensive new type of refrigerant. Techs can't find any leaks. Had a tech add this after a recharge. We will see how well it works in July.

What I liked about this, Adam is I put it in and did not even have to put any Freon in after putting this in

Worked great

The product seemed to work and AC felt better right off the bat but will have to wait how long and if it lasts. Instructions were unclear and safety recommendations also unclear. Not accessible if someone does not know how things work and such. Also labeling is confusing as to if the product has stop leak and refrigerant or just stop leak. Should be better

I placed the can in warm water for15 minutes as I do with all refrigerants to get a flow. I used a can of this company's freon (4oz) after vacuuming the system then I use the Stop Leak of the same company and my low-pressure gauge froze on 10 psi and never able to put another can. I used 3 cans of their 1234yf refrigerant on another unit the same day and the gauges worked fine.

This helped slow the leak, but did not fix it entirely. I am sure that one of the o rings / seals are back in my evaporator core but I was hoping it wasn't so back that I had to change it. Guess not everything can be fixed easily. Considering it made my freon last through the rest of the summer, I can say it wasn't a good product.
