You can use it in your brewing tanks, storage containers, etc. It attaches to a 1.5' tri clamp. The spray ball has a 1/2' MPT and is made from 304 stainless steel. The attachment part is 2.5 inches long and 0.75 inches wide. Remember, you'll need a pump that can reach at least 29 PSI to use it effectively, and the 1.5' tri clamp gasket and clamp aren't included.
