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

Es muy práctico y confiable

Love the kit it works well. Great value and very easy to use.

Grate tool for my works

Me trabajo muy bien.

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.

Great product for HVAC technician love it

Could not use product once due to cross threads where you input oil. Was not as described & cheaply made. Do not recommend.

Only lasted 8 months before it broke!! ugh
