So, I want to install a corny keg ball lock Gas post on/through a typical plastic fermenter bucket lid. (It's for carrying out an experiment relating to gas exchange. Can't say more, without spoiling it.) If anyone has done this (perhaps to facilitate closed transfers from a bucket or other plastic fermenter?), can you describe the fastening and gasket hardware you used? (Mainly looking for part numbers/sources.) Or, if anyone has done this with a stainless lid, I imagine I could adapt your design. TIA.
