O'ring DIN 3771.
Since the O-rings are cheap and simple sealing elements they have a wide application area in hydraulic and pneumatic systems. In case of providing suitable working conditions and equipments, they can be used both in static and dynamic applications. Because they occupy less space and provide two sided sealing compared with other sealing elements, O-rings enable easy designs. Having good results from O-ring applications is up to suitable measurements, choosing correct material, and proper surface quality of metal parts.
