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

It worked well

I recently purchased the Aupoko AC Oil Injector Kit with the R134A Oil Injector and R1234YF Low Side Quick Coupler, and I'm quite satisfied with its performance.First off, I must mention that I decided to buy this injector after seeing some positive reviews from YouTubers who specialize in automotive maintenance. The kit includes everything you need for injecting dye and oil into your AC system, making it a comprehensive solution for those who want to maintain their vehicle's cooling system themselves.One aspect that impressed me is the versatility of this kit. It's designed to work with various refrigerants such as R134A, R22, R12, and R1234YF. This means that whether you have an older car or a newer model, you'll likely be covered by this injector kit.However, my one minor gripe with this product is the lack of clear instructions on how to purge the air out of the injector. This is a crucial step to ensure proper functioning, and it would have been really helpful to have some detailed guidance included in the package. I ended up searching online for instructions, and fortunately, I was able to find some tutorials to guide me through the process.Apart from this small hiccup, the Aupoko AC Oil Injector Kit works like a charm. The R1234YF Low Side Quick Coupler is a convenient addition, making the connection process a breeze. The 1/4" SAE Connector also feels sturdy and well-made.Overall, if you're looking for an affordable and effective solution to maintain your AC system, the Aupoko AC Oil Injector Kit is a solid choice. Just keep in mind that you might need to do a bit of extra research to fully understand how to use it properly. With some clearer instructions, this kit would easily earn a five-star rating from me.

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 works great worked out my Honda Civic 2017 found the leak right away

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.

using car ac system to inject ac oil into ac system

was man sich damit in der Handhabung an Theater spart, ists das allemal wert ...Aus meiner Sicht macht sich das Teil selbst bei nur einmal benutzen bezahlt - absolut problemlos, und zumindest eine gefühlte Sicherheit ...Kaufempfehlung!

Very well made in my opinion, worked a treat.

Perfecto 👌

Item was faulty . Quick coupler had s metal ring stuck in it cant even use
