Lens Gaskets according to DIN 2696 are pure metal sealing elements. They consist of a ring-shaped, turned metal body with a lens-shaped sealing surface.
The lens-shaped sealing surface is clamped between two conical sealing surfaces of the flanges and creates a highly effective metallic gasket. Additional sealants are not required.
DIN 2696 ensures that Lens Gaskets can be precisely manufactured and reliably used in critical piping systems in the chemical industry, power plants and other high-pressure systems. Lens Gaskets are durable and low-maintenance.
