1)The o-ring can be used in static&dynamic applications, include rotating pump shafts and hydraulic cylinder
2)made from nitrite, neoprene, EPDM, silicon and viton (fluoroelastomer)
3)high oil and temperature resistance, low compression set, excellent physical properties, acid resistance
4)varied standard size and thickness in stock/according to custom request.

O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable, and have simple mounting requirements. They can seal tens of megapascals (thousands of psi) pressure.
