The O-ring is coated with a special process, and the outer layer of the sealing ring is coated with a layer of wear-resistant and corrosion-resistant material, so that it has better sealing performance, high temperature resistance, low temperature resistance and chemical medium resistance. This paper will introduce its characteristics and applications in detail to help people better understand and apply this reliable sealing element.

trait

1. Corrosion resistance: The outer material of the sealing ring can be made of different corrosion-resistant materials according to different working conditions, such as fluororubber (FKM). This enables it to run stably for a long time in the environment with strong corrosive chemical medium and prolong its service life.

2. High abrasion resistance: The outer layer of the sealing ring is usually made of materials with strong abrasion resistance, such as PTFE. This material has excellent wear resistance, so that it can better maintain sealing performance under high-speed movement or high friction conditions.

3. High-temperature resistance: High-temperature materials, such as silicone rubber (VMQ) and polytetrafluoroethylene (PTFE), are usually used to coat the O-ring. This material has excellent high temperature resistance and can maintain good sealing performance in high temperature environment.

4. Low-temperature resistance: For some low-temperature application scenarios, the sealing ring can be made of low-temperature materials, such as fluororubber (FKM) and polyurethane (PU). This makes it still maintain good elasticity and sealing performance in low temperature environment.

5. Aging resistance: The sealing ring is usually made of high-quality special materials, which has good aging resistance and can still maintain good sealing performance after long-term use.

6. Anti-compression deformation: The material of the outer layer of the sealing ring has good anti-compression deformation performance, and can still maintain a stable sealing effect under high pressure, which is suitable for high-pressure sealing occasions.
