What happens when a Tri-Clamp clamp is tightened too much?

When a TC clamps gets tightened too much, it’s most likely that the gasket between the flanges will be squeezed excessively. This will result into an unwanted deformation of the gasket and thereby, it will extend into the pipe or tubing. This creates a dead spot which is the ideal basis for deposits, biofilm and contaminations. It is absolutely mandatory to tighten Tri-Clamp clamps with the right amount of torque.
