This BrewZilla PPSU sight glass stainless steel ball valve and elbow use radial seal O-rings to form a strong, leak-free connection. Two in the ball valve and two in the bottom elbow. When assembling the sight glass to upgrade your existing Gen 3 or Gen 4 BrewZilla, you will reuse the female camlock x female 1/2" fitting that comes on the recirculation arm, or you need to purchase a separate fitting for the end of your custom build.
You will also need plumbers tape or food grade Loctite to assemble the ball valve with the camlock fitting.
Rather than purchasing the parts separately, Gen 3 and Gen 4 BrewZillas can be upgraded with one of these sight glass kits.
