I know understand how this all works. No instructions so the first time I winged it and it leaked. So, there are two silicone gaskets and two metal washers. You need to put one set on the outside and one set on the inside. The metal washer needs to be squeezing the silicone. Furthermore, there is a yellow cap thing I had no idea what it was for. However, it's for tightening the nut on the inside of the glass. Needs instructions or video!
