O-Rings are widely used in static and dynamic applications due to their simple shape and low prices. There is a wide range of applications in hydraulic and pneumatic systems with proper raw material choice. Groove dimensions must be carrefuly checked to ensure right o-ring selection. Otherwise the life of the o-ring will be shortened. We offer NBR as standard material for o-rings. However Viton, HPU and RSP materials are also available according to your system requirements. Under high pressure conditions, using support rings would prevent the O-ring of damages. Please contact with us for your special usage requirements.
