Works, hard to use

Reviewed in the United States on April 9, 2023

It's very hard on your hands to turn it and inject the oil. I ended up getting some pipe wrenches to force it in because it destroyed my hands. Seems to do the job though.

Squeezes oil into high pressure system

I was able to aqueeze some oil into the system that leaks 2-3 lbs per year. It got a sticky reverse valve functioning again. Paid for itself with first unit

Things are never what they seem until you see them up close.

The product I ordered looked like a piece of precision made equipment, bait and switch. That’s what took place here. The product shown on Amazon showed precision engraving graduations for measuring with this device. What I received is a decal or sticker showing graduations on the part, rather than engravings, very cheap substitution for what I paid for buyer beware. I will measure with other means before dispensing into the new receive device assuring correct values have been administered once again, what were subject to deal with due to failed quality control, and business ethics in our country today. sincerely retired machinist, Michael G Robinson Rancho, Mirage California.

This product came with a R134a low-side adaptor fitting. However, it didn't fit my 2010MY minivan's low-side port connection line. I had to use my ac manifold hose adaptor fitting instead. The unit didn't come with any instructions.
