    Hi, So here I am asking my first noob question. I bought a used compressor with a tank but the regulator did not survive the shipping thanks to FedEx. So I have ordered a new one and when I was looking at the pictures of it, I see the inlet and outlet, then there is the gauge on one side. On the opposite side of the gauge, there is another connection point that is sealed with a 1/4" hex head screw.

    My question is, what is that connection used for? Thanks for any information on that.

    Maybe you can flip the gauge over to the other side if you need to for space restraints or something.

    Can you post a picture? It would help us to help you. And helping is good.
    Whether it helps us or you.
    I’ve been drinking heavily so ignore me.
    Except for the post a picture part, that was a solid idea drunk or sober.

    Thanks guys for the replies and suggestions. My new regulator arrived today so I just took out that screw to see if it was any different than the other side and it is just the same. I guess it is so you can place a gauge on either side according to your preference. I was kind of hoping that it was for a gauge to monitor the tank pressure only. Mystery solved. ;)

    Just an extra outlet that is used to reconfigure the layout.
