Grommet processing

MacGuard (grommet) is the name of the option which applied SUS 316L caulking to the inner diameter and outer diameter of the gasket.
Adding MacGuard as an option of gasket makes it possible to greatly improve sealability, contamination countermeasure, pressure resistance, heat resistance, etc.
