Tri-clamp fittings, also known as tri-clover fittings, are a sanitary fitting for brewing and other applications. These connections use a gasket and clamp to connect two sides of a plumbing connection. Because they do not use threading and can be easily taken apart for cleaning and sanitation, they are perfect for brewing!
