1. Material selection

Nitrile rubber (NBR): provides good oil resistance and wear resistance, suitable for hydraulic systems, automotive fuel systems, etc.

Fluororubber (FKM): has strong high temperature resistance and chemical corrosion resistance, suitable for high temperature and corrosive environments, such as aviation, chemical industry and other fields.

Chloroprene rubber (CR): anti-aging, suitable for sealing applications in automobiles and industrial equipment.

Silicone rubber (SI): suitable for sealing at extreme temperatures, able to withstand working environments as low as -50°C to as high as 200°C.

Other special rubbers: such as EPDM, HNBR, etc., suitable for more specific chemical and environmental requirements.

2. Application areas

Hydraulic and pneumatic systems: suitable for sealing in hydraulic equipment and pneumatic devices to prevent liquid or gas leakage and ensure efficient and stable operation of equipment.

Automotive industry: widely used in sealing of components such as engines, fuel systems, air conditioning systems, etc., to reduce leakage and improve vehicle reliability.

Mechanical equipment: used for sealing pumps, compressors, valves and other equipment to ensure smooth operation of the equipment and prevent leakage of lubricating oil or coolant.

Chemical equipment: suitable for sealing in various chemical delivery pipelines to prevent chemical leakage and ensure safe operation.

Electronic and electrical industry: in electronic and electrical equipment, prevent the entry of water, dust and other substances to ensure the normal operation of the equipment.

3. Performance characteristics

High temperature resistance: This series of sealing rings usually have high high temperature resistance and can withstand working environments from -40°C to +200°C (or even higher temperatures) to meet the needs of high temperature equipment.

Corrosion resistance: using fluororubber, chloroprene rubber and other materials, the sealing ring has strong acid and alkali resistance, oil resistance, and chemical corrosion resistance, suitable for harsh working environments.

Anti-aging performance: good anti-ozone, anti-ultraviolet and anti-aging properties to ensure that the sealing effect is not affected during long-term use.

Wear resistance: The sealing ring has strong wear resistance and is suitable for use under high pressure and dynamic movement working conditions.

Excellent sealing: Provide strong static or dynamic sealing to prevent gas or liquid leakage, ensure sealing effect and efficient operation of equipment.

4. Specifications and sizes

Standardized sizes: ODU/IDU/KDAS series seals usually provide a variety of standard sizes to meet the needs of different equipment and sealing grooves. Common sizes include inner diameter, outer diameter, thickness, etc.

Customized service: According to the special requirements of the equipment, provide seals with customized sizes and materials to ensure the best sealing effect and equipment compatibility.

5. Installation and maintenance

Easy to install: This series of seals is simple in design and easy to install, suitable for various standard sealing grooves and connecting parts.

Regular inspection: When used in high temperature, corrosive environment or high pressure conditions, it is recommended to check the status of the seal regularly to prevent wear, aging or damage, which will affect the sealing performance.

Replacement cycle: Depending on the use environment and frequency, the seal may need to be replaced regularly, especially under extreme conditions, to ensure the sealing of the system and the stability of the equipment.
