The Boil "T" screen is perfect for commercial Sanke kegs, brew pots, or square coolers! The 304 Stainless 12" mesh screen can act as a trub filter in your boil kettle to prevent clogging in your ball valve and tubing. Also works well as a false bottom alternative, while being less expensive. The 1/2" copper tee in the middle requires soldering to your valve connection.
