Static sealing for chemical, pharmaceutical, food and sanitary equipment against strong corrosive media.
Rubber O-rings are circular elastomer seals. They are designed to prevent fluid or gas leakage between mating surfaces.
They serve both static sealing (no movement between parts) and dynamic sealing (reciprocating, rotary or oscillating motion).
Typical applications include hydraulic cylinders, pneumatic valves, automotive engines, pumps, pipe fittings, compressors, household appliances and equipment for food, medical and chemical industries
Static sealing for chemical, pharmaceutical, food and sanitary equipment against strong corrosive media.
