Taper-sealing gasket widens usable diameter of connected ports.

Conventional gasket is sheared by the penetration of knife edges during a process of flange tightening. The tightening force which is loaded with securing bolts is considerably consumed in the shearing the gasket. As a result, formed seal area becomes small consequent on the waste of tightening force. Higher tightening torque is required to obtain sufficient seal area.

Usable diameter of connected tubes with Taper-Sealing gasket is a full diameter of the connected tubes. It is favorable to insert equipment of larger diameter ( Q-mass, manipulators, etc.) into smaller vacuum ports.
