How to recover the deformation of rubber sealing ring

The deformation of rubber seal ring can be divided into recoverable deformation and irrecoverable deformation. Recoverable deformation is slight deformation, such as small amplitude bending, twisting and  Irrecoverable deformation is severe deformation, such as crease, fracture, etc.

The rubber seal ring with slight deformation can be used normally after its shape is restored without loss of sealing function, while the rubber seal ring with serious deformation can not be used normally even after its shape is restored.

The rubber sealing ring will be slightly deformed when it is stored for a long time. How to recover the deformation of rubber sealing ring?

1. Take out the deformed rubber sealing ring, boil a pot of water quickly with heat, and pour it into the container.

2. After pouring boiling water into the container, soak the rubber sealing ring in boiling water.

3. After soaking for a few minutes, take out the rubber sealing ring and pull it by hand.

4. After pulling, it will be OK to restore the elasticity, so that the rubber sealing ring will return to its original shape.
