Causes of O-ring damage

1. The friction between the seal and the metal surface causes the seal to wear.
Contaminants in oil (especially metal particles). Factors such as too high roughness on the metal surface and too tightly packed. The friction between the seal and the metal surface causes the seal to wear. Contaminants in oil (especially metal particles). Factors such as excessively high roughness on the metal surface and too tightly packed accelerate this wear.


2. Squeeze deformation
The seal liquefies under high pressure and enters the gap of the sealing surface. The relative movement between the seal and the seal groove will facilitate this process. The squeezing of the gap causes the seal to be completely damaged, the surface is torn or broken, and plastic deformation may occur. Add sealing ring to avoid extrusion.
