Precautions

The above installation holes, chamfer dimensions, and fastening torque are reference values.

The sealing effect varies depending on the usage environment. In addition, as the size of the installation holes and chamfers increases, the sealing effect will weaken, so it is recommended to minimize the size of the installation holes and chamfers as much as possible.

The bolt may reach the allowable torque before the metal part of the sealing gasket comes into contact with the mating material. Please pay attention to the torque when tightening.
