If you are looking for an easy way to make your own mash tun or lauter tun these 30cm false bottom will do the job nicely. They are made from 304 Grade stainless steel, come with a 1/2 inch elbow and also have a stainless steel barb with 13mm OD so it's suitable for the heavy duty silicone that we also sell or any other tubing that is 11-13mm ID. The 1/2 inch thread is also perfect as it enables you to remove the barb and fit various other fittings such as camlock fittings to this elbow.
