R1234YF & R134A AC Oil Dye Injector Kit with 2 Snap Quick Couplers 2 Oil Checkers 2oz Measuring Cup

Works amazing and helps me inject oil with UV dye into automotive AC systems for diagnosing tough to find leaks. The construction feels solid and the tool is effective and leak-free, simple to use. What more can you ask for?

Works great! Well built and can be used for all kinds of applications

I love this tool. Its alot better then that plastic one that cost 15.00. Great product love it

The product is well built. The top unscrews to allow you to add the oil or dye.

Overall, the injector seems to be of decent quality. It seems like they added a low-loss fitting (check valve) to the end of the outlet hose, where before they were shipped with an open fitting. The check valve does make it easier to not leak oil out of the hose while connecting, but it makes it harder to purge the air out of the hose. All in all not a huge problem but requires some rigging to purge.The main problem I have is that none of the quick disconnects that come with the injector thread far enough into the check valve to depress and open it. So the bundled quick disconnects are not usable with this injector. They work with my manifold hose however so I do have a use for them and I have another quick disconnect that does work with the injector, so I can make this work. However, someone ordering just this kit is not going to be able to use it for the intended purpose.

This thing is built to last!

Biggest piece of junk and a total waste of money! If I could give it negative stars I would. Don’t waste your money and time on this junk!

Works great
