KLINGER® Lens Gaskets

The proven high pressure seals

Lens gaskets are reusable, as the sealing effect is gener­ally achieved by elastic deformation of the surfaces.

Lens gaskets are impervious to overpressure. With increas­ing loads, the contact surface between the spherical lens surface and the spherical flange groove 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.
