Seals are a very common type of rubber component, but there are usually some problems that may arise. Let's take a look at what these problems are?

Wear and tear: The wear of seals involves the surface smoothness of the mating parts, the speed of movement, and the transmission medium, etc. Different sealing materials also adapt to different speeds;

Hardening: The seal itself is actually a material that hardens after being affected by temperature. Whenever the degree of hardening is too high, the seal cannot fill the gap between the fitting parts and will slowly leak;

Corrosion: The manifestation is usually caused by the softening of the seal, leading to dissolution. The reason is that the seal is invaded by the medium and the selected material is incorrect. If the medium contains water or solvents, special attention should be paid;

Extrusion: Every time the seal is subjected to excessive pressure, it will be squeezed into the gaps of the metal, causing leakage if the seal is damaged. This situation involves the hardness of the seal itself and whether the gaps between the metal are too large. If not handled properly during design, processing, selection, or installation, it can be damaged. From this perspective, no matter how good the quality of the seal is, it is necessary to consider possible problems and try to avoid unnecessary risks as much as possible!
