I got everything for my 10G MT build from Home Depot. A 1.5"x.5" nipple to go through the wall, a fender washer that fits over the nipple and two .5" conduit lock-nuts. The nipple goes through the rubber gasket that the spigot sat in, through the wall of the MT with the washer on the inside of the MT. One lock-nut inside the washer, between it and your screen. The other on the outside of the MT between the wall and the valve.
