■Features

◆Since the gasket of this type is formed to seal loop having a concentric circle shape, it assures the excellent sealing performance even at low-torque tightening.

◆Since the gasket of this type assures the increased compression rate when applying the tightening load, it assures the excellent follow-up performance against the equipment side accuracy.

◆The gasket of this type assures the heat-resisting performance, and provides the excellent sealing performance for a long time because of its material configuration.
