    Shape classification of silicone sealing ring?

    The shape of the silicone sealing ring can be classified according to its cross-sectional shape and use. The following are the shape classifications of some common silicone seal rings:

    Silicone O-ring: O-ring is the most common type of sealing ring, its cross-sectional shape is circular, and can be used for static sealing and dynamic sealing. It is usually placed in a cylindrical or conical trough to enclose liquids or gases.

    Silicone X-shaped sealing ring: The cross-sectional shape of the X-shaped sealing ring is X-shaped, similar to the connection of four O-shaped sealing rings. It is more suitable than O-rings for some high-pressure, high-temperature and high-friction applications.

    Silicone Square seal ring: Square seal ring has a square cross-sectional shape and is usually used for special sealing applications, such as those that need to withstand large deformation or high pressure.

    Silicone Flat seals: Flat seals have a rectangular cross-sectional shape and are typically used in static sealing applications, such as in flanged connections.

    Silicone V-shaped sealing ring: The cross-sectional shape of the V-shaped sealing ring is V-shaped, which is suitable for sealing on the rotating shaft and can prevent liquid or impurities from entering.

    Silicone U-shaped sealing ring: The cross-sectional shape of the U-shaped sealing ring is U-shaped, which is suitable for static sealing and dynamic sealing, especially for hydraulic applications.

    Silicone L-shaped sealing ring: The cross-sectional shape of the L-shaped sealing ring is L-shaped, which is usually used for sealing the rotating shaft, similar to the V-shaped sealing ring.

    Silicone Braided seals: Braided seals are braided from thin wires, which can be adapted to larger sizes and special sealing needs.

    Silicone Bellows-type seals: Bellows-type seals are usually used in highly dynamic or high-temperature environments, and their special bellows structure can withstand axial and radial movements.

    What are the requirements for the level of silicone used in different places for silicone sealing rings?

    In different application scenarios, the requirements for silicone sealing rings may vary due to their use, working environment and performance requirements.
    Medical devices: In medical devices, silicone seals may need to meet stringent medical-grade standards to ensure product biocompatibility, drug resistance, and sterility. This means that the silicone material used must pass strict biocompatibility tests and must not release harmful substances.
    Food processing: In equipment that comes into contact with food, silicone seals may need to meet food-grade standards to ensure that their materials will not contaminate food and will not affect food safety and quality.
    Automobile industry: Silicone sealing rings used in automobile engines, transmissions and other parts may need to have high temperature resistance, oil resistance and vibration resistance to adapt to the complex working environment of automobile engines.
    Electronic and Electrical Equipment: Silicone gaskets used in electronic equipment need to be dust-tight, water- and chemical-resistant to protect internal components from the external environment.
    Industrial equipment: In industrial equipment, silicone seals may need to withstand high pressure, high temperature or chemical corrosion, so it is necessary to choose silicone materials with corresponding resistance.
    Aerospace: In the field of aerospace, silicone sealing rings may need to meet strict requirements for high temperature resistance and radiation resistance to ensure performance stability in extreme environments.
    Household items: Silicone seals used in household items may need to be safe, non-toxic and not harmful to the home environment.
    The requirements for silicone sealing rings in different application fields may involve the performance of different aspects of silicone materials such as biocompatibility, chemical stability, high temperature resistance, wear resistance, oil resistance, and corrosion resistance. Therefore, when selecting a silicone sealing ring, it is necessary to select the appropriate silicone grade according to specific application requirements and environmental conditions to ensure that the sealing ring can perform optimally in a specific working environment.

    Maintenance of silicone sealing ring?

    Proper maintenance of the silicone sealing ring can prolong its service life and maintain its good sealing performance. Here are some suggestions for silicone seal care:
    Periodic inspection: Regularly inspect the appearance of the silicone seal for signs of damage, aging or deformation. If any abnormality is found, the sealing ring should be replaced in time to avoid leakage.
    Keep Clean: Keep the working area of the silicone seal clean, and regularly remove any dust, dirt or chemicals attached to the seal. This prevents these impurities from affecting sealing performance.
    Avoid Excessive Stretching or Compression: During installation or operation, avoid excessive stretching or compression of the silicone gasket to prevent it from being damaged or losing its elasticity.
    Avoid excessive use of lubricants: While some lubricants can help reduce friction on seals, using the wrong lubricant can damage the silicone material. Make sure to use a lubricant that is compatible with silicone.
    Avoid exposure to extreme environments: Silicone seals are generally resistant to high temperatures and chemicals, but they should still be avoided from exposing them to extreme temperatures, chemicals, or environments beyond their tolerance.
    Avoid violent vibration and impact: severe vibration and impact may damage the silicone sealing ring, so try to avoid it during use and operation.
    Note storage conditions: If you need to store the silicone seal, it should be stored in a dry, cool place away from direct sunlight and chemicals.

    Follow the custom silicone manufacturer recommendations: Different models and brands of silicone seals may have different usage and maintenance requirements, so the manufacturer’s recommendations and instructions should be followed when using them.
