FLASH LESS IMPORTED O-RING
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.
If there is no permissible gap in static applications, for O-rings there is no certain pressure limit to resist against. But, it is required that tolerances should be chosen correctly and xing screws should not create any gaps by extending in high pressures.
They are used in low dynamic pressures and similar others like pneumatic cylinders or valve spool.
The other two most important factors in dynamic and static sealings are housing and the surface quality worked on.
For dynamic applications, a better surface quality is required compared with static ones.
