Review on Aupoko Injector Refrigerant R 134A Coupler by Stephen Johnson

Used to inject Pag oil into my system. worked fine As well as the fact that you don't need to connect anything else to force oil or paint into the system. I had no trouble connecting the connector to my system. just fits well. The only thing I have is reading Oz. My label is a self-adhesive sticker. It is NOT engraved. It's not so bad now, but I think over time he'll start running around and not being able to read. Etching would be a little better in this case.
