Can O-rings in hydraulic systems be used as dynamic seals?

O-rings are indeed designed to function as both dynamic and static seals within hydraulic systems. They are utilized in applications where there is relative motion between two surfaces, making them effective for dynamic sealing purposes. The elasticity and compressibility of O-rings allow them to maintain a seal despite the movement, effectively preventing fluid leakage even under varying pressure and temperature conditions.

Additionally, O-rings can be made from various materials that enhance their compatibility with different hydraulic fluids, which is crucial when operating in dynamic environments. Their ability to seal effectively in situations where a linear or rotary motion occurs is a key characteristic that defines the functional versatility of O-rings in hydraulic systems.
