Premium O-ring for oil and gas service. Excellent resistance to oil, gas, high pressure and extreme temperature. Metric and AS568 sizes available. Custom specs supported. Suitable for wellhead, pipeline and downhole equipment sealing.
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
