O Ring

O ring is a fundamental component in the industrial sealing field, widely used in various sealing applications. In hydraulic systems and pneumatic systems, the O-ring leverages its own elastic deformation to fill sealing gaps effectively, playing a key role in preventing the leakage of liquids and gases.

For instance, between the cylinder piston and the cylinder barrel, as well as at the threaded joints of pipe fittings, the O ring is essential for achieving reliable static sealing or dynamic sealing.

Additionally, O rings can effectively prevent media penetration into the sealing parts of key equipment such as valves and pumps, ensuring the integrity of the sealing system. Moreover, O ring seals can also buffer vibrations and absorb impacts to a certain extent, thereby enhancing the stability of industrial equipment. Therefore, seals play a very important role. Rubber seals, whether in hydraulic systems, pneumatic systems or other industrial machinery, are the first choice to meet industrial needs.

We have plenty of materials for you to choose from. For instance, nitrile rubber (NBR) is durable and often used in automotive machinery, oil seals and similar fields. Silicone (SI) can stand high temperatures well and has good elasticity, so it’s suitable for food-grade equipment. Then there’s fluororubber (FKM), which is resistant to high temperatures and corrosion, used in chemical industry, aerospace and other such areas. EPDM rubber (EPDM) is anti-aging and resistant to acids and alkalis, commonly found in doors, windows and industrial equipment. Of course, there’s also natural rubber (NR)—it has good elasticity but isn’t oil-resistant. If you need other materials, please contact us.
