I used this manifold to create a vacuum and fill a car's r134A AC system. It worked without any problems. It comes with adapters you need to connect to a vacuum pump. You need to buy a glass faucet when using self-closing jars like r134a. It comes with an adapter that you also need to connect to the tap. I'm not an AC pro, but this manifold seems to be of pretty good quality.
