Tri-clamp fittings, also known as tri-clover fittings, are commonly used in professional brewery settings due to the sanitary connection made by using a gasket and clamp to connect two fittings together. These fittings can easily be broken down for cleaning and sanitizing, and do not contain any tricky threads where dirt and bacteria can hide. This particular fitting is a 90 degree 1/2 in. barb fitting. You can attach 1/2 in. tubing to this barb for recirculating, transferring, or whatever you need! Tri-clamp fittings make it easy to quickly break down your brewing setup for cleaning and sanitation. Get on board with tri-clamp fittings today!
