Rubber sealing grommets

A rubber sealing grommet is a seal made of rubber material that is commonly used to provide a static or dynamic seal. Rubber sealing grommets are usually made of rubber materials, such as nitrile butadiene rubber (NBR), ethylene propylene rubber (EPDM), silicone, etc. Rubber sealing grommets are generally ring-shaped, with cross-sectional shapes such as circular, square, and V-shaped. They are simple in structure and usually consist of a rubber seal, sometimes combined with a support of metal or other materials. The main function of the rubber sealing grommet is to provide a sealing effect and prevent the leakage of liquid or gas. They can be used for static sealing, such as filling gaps, pipe connections, valve seals, etc.; they can also be used for dynamic sealing, such as piston rod seals, shaft seals, etc. Rubber sealing grommets are widely used in the automotive industry, machinery and equipment, electronic products, aerospace and other fields. They are used for sealing pipes, valves, pistons, shafts and other components to ensure reliable operation of the system under various working conditions.

A rubber grommet is an annular seal made of rubber material used to provide sealing properties at joints or seams. It is usually made of rubber materials (such as NBR, EPDM, silicone, etc.) and has good elasticity and durability.

Structure

Rubber sealing grommets are usually ring-shaped and constructed of soft rubber material. Its inner and outer diameters are adapted to the dimensional requirements of the connection points or seams.

Elements of structure

  • Cross-sectional shape: The cross-sectional shape of the rubber sealing grommet determines its sealing performance and scope of application. Common cross-sectional shapes include round, square, V-shaped, U-shaped, X-shaped, etc. Different shape designs enable rubber sealing grommets to adapt to different sealing needs and application scenarios.
  • Material selection: Rubber sealing grommets are usually made of rubber materials, such as NBR (nitrile butadiene rubber), EPDM (ethylene propylene rubber), silicone, etc. The selection of materials depends on the requirements of the application environment, such as oil resistance, high temperature resistance, chemical corrosion resistance, etc. Rubber materials have good elasticity and sealing properties and can adapt to different working conditions.
  • Elastic properties: The elastic properties of rubber sealing grommets are key to their sealing performance. They have a certain compression deformation ability and can adapt to different sizes and shapes during installation to achieve a reliable sealing effect. The elastic properties of rubber sealing grommets also resist the effects of external factors such as vibration, shock and temperature changes.
  • Dimensions and Dimensional Tolerances: Dimensions and dimensional tolerances of rubber sealing grommets are important factors in ensuring that they match the connecting components and install a seal. Appropriate size and tolerance design can ensure that the sealing grommets fit tightly with the connecting parts during installation to achieve an effective sealing effect.
  • Surface treatment: In order to improve the sealing performance and durability of rubber sealing grommets, special treatments are often performed on their surfaces. This may include the application of special lubricants, treatments to increase wear resistance, or anti-corrosion treatments. Surface treatments improve sealing grommet life and performance.
