Fluids/chemicals with their compatibility ratings for use with the most common O-Ring materials

O-ring sealing sets made of VITON®, EPDM, KALREZ®, CHEMRAZ® or PERLAST® for the bead mills DISPERMAT® SL and SL-nano

The DISPERMAT SL are supplied with VITON (FKM – rubber) O-rings as standard. Alternatively EPDM (ethylene propylene) O-rings can be fitted at no extra charge.
If VITON or EPDM is not compatible with the products being milled, O-rings made from one of the following perfluoroelastomeres are recommended: KALREZ®, CHEMRAZ®, PERLAST®



The following compatibility guide should help you to find the right solution.
