KLINGER Lens Gaskets

Lens seals are impervious to overpressure. With increasing pressure, the contact surface between the flange surface and the lens gasket increases, so that the surface pressure only increases to a lesser extent.

We can also specially produce bellows lenses, lens blind spectacle gaskets and half-lenses. Lens blind spectacle gaskets are made of a sealing lens and a lens blind, which are connected by a ligament. It is also usual to use lens blinds on their own. In this case, it is useful to weld on a small plate to render the lens blind distinguishable.
