The bazooka screen is the perfect thing to easily upgrade a pot with a 1/2" ball-valve into a boiling kettle complete with a hop filtering screen. This is a 12" long screen with a 1" diameter constructed of stainless steel, grade 16 mesh. Complete with a stainless steel 1/2" male pipe thread fitting that will thread right onto the Weld-free Ball valve or the Polarware pots we sell. Will attach to any 2-way port that is 1/2" pipe thread, no tools or welding required! Because of the smaller surface area, the Bazooka screen is not very suitable to building a mash or lauter tun for filtering grains. A false bottom will perform much better.
