Due to its spherical shape and relatively small sealing area, the seal achieves a high specific pressure during installation and thus very good sealing properties.
The spherical shape and relatively small sealing area of the gasket allow it to achieve high specific pressure during installation and thus very good sealing properties.
Lens seals withstand high specific pressure and are therefore safe against "overstressing". Further advantages are the virtually complete resistance to ejection of the seal and the larger contact area compared to RTJ seals.
Lens seals require a corresponding shape of the sealing surface of the flange, most often a conical shape with an opening angle of 140°. The spherical shape of the seal gradually deforms relative to this surface as the gauge pressure increases, thus increasing the real sealing area.

We can create the perfect seal for your needs, including non-standard sizes.
Metal core seal combined with a soft sealing layer of graphite or PTFE. For use in high pressure and heat stressed flange joints.
It solves the problems caused by insufficient elasticity of the seal. Also suitable for applications with low initial tightening torque.
It solves the problems caused by insufficient elasticity of seals and prevents the leakage of pollutants into the environment. Suitable where cooling and re-heating of the flange occurs.
The metal sealing rings are designed for high pressures and temperatures - they can seal joints with pressures up to 1500 bar and temperatures up to 1000 °C.
Metallic coated gaskets are produced in various combinations of metallic and non-metallic materials. Use in a wide range of industrial applications.
Based on the analysis of our engineer, we will suggest the most suitable solution and supply all necessary material. The installation of the joint will then be carried out by our expert Torque Service
Designing optimal seals for your operation We will be happy to analyse the sealing solution for your equipment and recommend possible optimisation. We perform the analysis for all types of seals. Fla
