lens ring joint gasket is a line contact seal for use in high pressure piping systems and in pressure vessel heads. The lens cross section is a spherical gasket surface and requires special machining on the flanges. Since the contact area is very small and gasket seating pressures are very high, the gaskets will seat with a small bolt load.
Lens ring joint gasket is manufactured in accordance with DIN 2696, provide the engineer with a high integrity, high pressure and temperature seal for special applications.
Lens rings have a spherical surface and are suitable for use with conical flange faces. So other styles are available on request.

Prime Features
As the standard, the gasket material should be softer than the flange material, thus ensuring that the applied compressive load leads to the elastic and plastic deformation of the lens ring and not the flange sealing face
As with all metallic joints, the re-use of lens rings is not recommended.
