The sealing ring is an important component of hydraulic jacks, generally made of rubber or rubber composite materials. High quality hydraulic jack sealing rings need to have a certain degree of elasticity. So why do hydraulic jack sealing rings need to have a certain degree of elasticity?

Elasticity is one of the basic requirements for effective sealing of sealing rings. When the sealing ring is placed between two connecting components, it will be squeezed or compressed. Due to its elasticity, the sealing ring can fill the small gaps between connecting components, preventing the leakage of liquids or gases.

Elasticity enables the sealing ring to adapt to surface irregularities, minor defects, or deformations between connecting components. Regardless of the shape of the connecting components, the elasticity of the sealing ring enables it to tightly adhere and provide effective sealing effect.

In some applications, connecting components may be affected by vibration or impact. A sealing ring with certain elasticity can maintain sealing performance under vibration or impact, preventing liquid or gas leakage.

These are the key to the elastic function of the sealing ring, and it is precisely under this characteristic of the sealing ring that the hydraulic jack ensures the normal transmission of the hydraulic system and avoids the occurrence of hydraulic oil leakage.
