Note
O-rings are universally applicable sealing elements for sealing against liquid or gaseous media. They are suitable for static and subordinate dynamic applications. O-rings can be installed for both radial and axial sealing. The sealing effect results from the axial or radial compression of the cross-section during installation. When installed, the pressure of the medium increases the deformation of the O-ring, improving the sealing effect. For optimum sealing, O-rings with the largest possible cord thickness should be selected.
During installation, care must be taken to ensure correct groove size, compression, expansion and/or compaction.
Relative to the O-ring inner diameter, the following should not be exceeded
max. 6% expansion
max. 3% compression.
FKM has very good resistance to ozone, oxygen, ageing and weathering. It offers very good thermal and chemical resistance, as well as low gas permeability, making it suitable for high vacuum applications. It is also flame-resistant and has a low compression set.
Chemically, FKM is highly resistant to mineral, vegetable and animal oils, fuels, many alkalis, acids and solvents. However, it is less resistant to polar solvents, certain alkalis and superheated steam.
The suitability for the respective application must be checked by the user.
