  • Silicone oil seals, which are also called VMQ, have strong resistance to temperature, which ranges from -140 degrees Fahrenheit to 392 degrees Fahrenheit. They are also resistant to ozone, light, and harsh weather conditions. Silicone is frequently used in hydraulics and pneumatics, as well as in the food and medical industries. Due to the material’s transparency and flexibility, it’s commonly chosen for the manufacturing of o-rings, molded parts, and flat seals, as well as electrical insulators.

  • 3. Fluid types: Oil seals interact with oils, fuels, grease, water, and more. Choosing a seal material that is most compatible with your chosen medium can help to increase the durability of the seal and its internal components.

  • The numbers 30-50-10 indicate the dimensions of the oil seal, specifically its inner diameter, outer diameter, and height. This measurement ensures that the oil seal fits perfectly into the designated space and effectively seals off any potential leaks.


  • In the realm of machinery and equipment, the oil seal serves as a vital component, ensuring smooth operation and extending the life of the system. This tiny yet indispensable device is designed to prevent the leakage of fluids, such as oil and grease, while allowing for the rotation of moving parts.
