Aupoko AC Oil Injector Kit for R134A R22 R12 R1234YF Refrigerant System

It’s good quality and does the job. Happy.

It worked well

Only used it once so far. Worked flawlessly. Only issue I believe the aluminum cylinder was used. Someone used channel locks to tighten the bottom of the cylinder. After using it I noticed it had a small leak at the bottom of the cylinder. Not enough to warrant a return. Other than that it did the job.

I have used it four times. I have used it for oil and Stop leak. Very solid made well, heavy duty would highly recommend.

This made it really easy to add oil to an AC system already charged with refrigerant. The R-1234yf low side coupler fit perfectly and I didn't have any leaks from any part of the injector.

Great tool and easy to use. It helped me find a leak in my ac system.

product was easy to use and great value
