The O-ring is the most popular form of seal
It achieves static sealing against liquid and gas mediums in mechanical parts. The selection of the suitable O-RING material plays a determining role in the operation and life against mediums such as fuels, oils and grease as well as in durability under mechanical forces.
NBR, HNBR, Natural Rubber (NR), Silicone rubber (VMQ), Viton (FKM), Viton Extreme-ETP (FEPM), Ethylene propylene rubber (EPM), Ethylene propylene diene natural rubber (EPDM), Polyurethane natural rubber (AU), PTFE, Fluorosilicone natural rubber (FVQM), Perfluor-natural rubber (FFPM), Fluoro natural rubber (FPM), Chloroprene-natural rubber (CR), Butyl natural rubber (MR), Aflas® (FEPM), KALREZ –Perfluoroelastomer (FFKM)
Both have an elastic core made from silicone (VMQ) or Viton (FKM), which offers the required elasticity, while the coating offers outstanding resistance against a wide range of chemical media
Fluorinated Ethylene Propylene (FEP)-encapsulated O-rings (-60° to 204°)
Perfluoroalkyl (FAP)-encapsulated O-rings (-60° to 260°)
Customized Material Solutions approved and widely used in food/pharma/chemical applications.
Stircomatic: These are seals mainly designated for use in valves in hydraulic system controls
Back Up Rings: For the protection of O-RINGS in high pressures.
Multi seals: metal-elastic seals for spirals, gasket joints/screw joints
Quad rings: Special profile seals for static and dynamic applications when O-RINGS are not sufficient.
