Seal Selection and Operation Range

The wide variety of types provide the opportunity to meet all sealing requirements for axial and radial seals. Not all maximum stresses can be applied to the seal at one time.

The variety of designs,jacket and spring materials, together with several springs and dimensions allow sealing applications within the following working ranges:
Temperatures from -250°C to +316°C
For rotation and reciprocating movement up to 5 m/s
For static applications up to 3500 bar pressure
For dynamic applications up to 550 bar pressure
Universal chemical-resistant
For vacuum and UHV applications
Diameter from 2 mm up to 3000 mm
