- Lens Ring
Tecson Lens Ring Gaskets are reliable gaskets for high pressure applications. They are re-usable also as the sealing effect is brought about almost entirely by elastic deformation of the gasket surface.
Description
Lens gaskets are also insensitive to over loading. Increasing the load on the gasket joint leads to an enlargement of the contact area between the spherical lens surface and the conical flange groove so that the increase in unit compressive load is less than aproportional one.
