Hello guys, Im new to the forum but I have been reading for a while now and recently came across a question (or an issue) that I could use some advice for. I bought a BluVac micron gauge the other day and I am trying to hook it up to my manifold set. Correct me if I am wrong but I would like to find a way to have the micron gauge between the low side valve on the manifold and the low side service connector. The only thing I can think of is to find a T that I can install on the gauge manifold low side that goes from 1/2" acme thread female out to 2 ports of 1/2" acme male (1 to connect the blue hose onto and the other would still have to convert to 1/4" flare female that the BluVac gauge has). After the "T" I would install a valve so that the micron gauge does not see pressure or oil. Does anyone have any ideas or pictures of how this can be done? I went to Grainger with my stuff and they were completely lost, the guy didnt even know that they were a/c gauges. Also went to a couple other places and they had no ideas. Thanks in advance for any help!!
