Good item, no leaks, quality made, but doesn't have any marks to know where the 1 or 2 ounce line...would be nice if they say something on the instructions book. I was afraid of over/under filling. When time is money, I don't have time to look for a measuring cup. One star off for that

Used to inject 1oz of PAG oil to my ac system. It works very well and arrived on time. Please not you will need to buy separate adapters to get this to work with your gauges. The two adapter specifications can be found in one of the earlier reviews. Aside from that, this worked perfectly well for my application.

Does everything you would expect it to do. We use it in the field on heavy equipment and it can hold up to being stored in a mechanics truck and that is saying something.

Works inconsistently, not really a problem with this specific problem. Probably just get a syringe style injector instead.

Definite brand new clean proper part. Stayed completely sealed when under pressure. Does exactly what it claims to do. Poor quality instructions. The oil only flows in one direction, which is not in the instructions. John W.

Nice no-nonsense precise way of adding oil to your a/c system when you have a manifold gauge set. Worked perfectly as described.

very usefull tool if you are working on your AC system and need to add oil. If your car is R134a you will have to get 2 adapters R12 to R134a 1x 1/234; ACME Female to 1/434; flare male 1x 1/234; ACME Male to 1/434; flare female Good quality adapters are not cheap around 20$ each. Follow the instructions, need to have a can of R134a to be able to inject oil or dye into the system
