Thought the problem was with the car, turns out the o ring wasn’t functioning. Replaced the o ring and now works, unfortunately trying multiple things to get the ac to work.Assumed the product was A+ and wasn’t.

Bought this product to vacuum test a mini split. Be sure to use tape on treads and tighten hoses and this product will do its job!

I bought this to recharge my Jeep and the vacuum pump works Great the Gages are ok The rest well I don’t care for much but that just me I think for the price it’s a good deal but if your going to use it much you will be upgrading some of the pluming like new fittings for freon tanks but that’s just me. This is a good all in one package for most who only need it now and then I gave it 4 STARS because of the fittings.
