EPDM.

Shore hardness ~ 70, black.

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.

The material EPDM has good chemical resistance, meaning that it can also be used in contact with CIP/SIP media. Its properties include high weather and moisture resistance, ozone resistance, high thermal resistance, high elasticity and good ageing resistance. It is resistant to e.g. polar media such as water (hot water and steam), alcohols, glycol-based brake fluids, detergents, caustic soda and potassium hydroxide solutions.

The suitability for the respective application must be checked by the user.
