These stainless steel Bazooka screens can be used in your mash tun or kettle. They are 1 inch in diameter come in various lengths and with either male or female NPT connections at the end for threading into welded or weldless ports or nipples.
The screen is quite rigid and will not collapse under a mash like the braids pulled from plumbing tubing do. The mesh size is 16 wires per inch which makes it easy to clean but will also keep out grains and leaf hops for easy runoff from your tun or kettle.
