Rubber Fab Gold Identifier Clamps have the same design and function as traditional 13MHHM Single Pin Heavy Duty Clamps, but they give you the ability to quickly "identify" certain connections in your process stream. These cross hole wing nut style sanitary clamps allow for quick and easy tightening without the need for tools, although Rubber Fab is proud to offer the Torque Tee Universal Sockets. These wingnut sockets can be used with a standard 1/4" drive torque wrench to guarantee proper clamping pressure is applied to your connection, ensuring a leak free seal.
