How It Works

The 13MHHM Single Pin Clamp is used to join two separate tri-clamp ferrule ends together, creating a secure and leak-proof seal when combined with a matching gasket--. The single pin hinge allows the clamp to open and close around the fitting connection-. The solid wing nut is then tightened by hand to the recommended 25 in-lb torque, compressing the gasket between the ferrules to form a reliable, sanitary seal. The serrated wing nut design ensures consistent grip even in wet or oily environments.
