Characteristics：

• Material resistance to chemical corrosion: FKM material has excellent resistance to oil, solvents, and chemical corrosion. This makes AS568 FKM 90 back-up rings ideal for sealing applications requiring use in harsh chemical environments.

• High-temperature stability: FKM materials can maintain their material properties in high-temperature environments and have high thermal stability. FKM 90 Back-Up Rings provide reliable sealing performance under high-temperature conditions and are suitable for high-temperature applications.

• Compression deformation resistance: Due to the presence of the back ring, FKM 90 Back-Up Rings are able to provide additional support and stability and resist compression deformation. This helps ensure the seal maintains its shape and function in high-pressure environments, increasing seal reliability.

• AS568 Compliant: AS568 is a commonly used O-ring sizing and coding system standard with a wide range of applications. AS568 FKM Back-Up Rings comply with this standard and therefore can be used with other AS568-compliant seals and accessories, providing interchangeability and versatility.

Function:

• Support function: Back-up rings are placed on both sides of the O-ring to provide additional support and prevent the O-ring from being squeezed or deformed under pressure loading. They maintain the shape and size of the O-ring, ensuring the effectiveness and reliability of the seal.

• Reduce friction and wear: When in contact with the sealing surface, it can reduce friction and wear between the O-ring and the sealing surface. They provide a smooth surface that reduces friction between the seal and surrounding components, extending the life of the seal and equipment.

• Auxiliary sealing: Back-up rings play the role of auxiliary sealing in the sealing system. They prevent media from leaking or penetrating behind the O-ring, ensuring seal integrity. This is particularly important in applications where hazardous materials or high-pressure media are handled.

Automotive Industry: AS568 FKM 90 Back-Up Rings can be used for sealing applications in automotive engines, transmission systems, and hydraulic systems. Due to the high temperature and pressure requirements of automotive engines and transmission systems, the high temperature and chemical resistance of FKM materials make back-up rings an ideal choice.

Chemical and petroleum industries: In the chemical and petroleum industries, FKM 90 back-up rings are used to seal equipment such as containers, pipes, and valves. Due to the various chemicals and high-temperature conditions present in these application environments, the chemical resistance and high-temperature stability of FKM materials allow them to provide reliable sealing performance.

Pharmaceutical Industry: In the pharmaceutical industry, FKM Back-Up Rings are commonly used to seal pharmaceutical handling equipment and containers. The chemical resistance and high-temperature stability of FKM materials are critical to maintaining the purity of pharmaceutical products and preventing leaks.

Food and Beverage Industry: In the food and beverage industry, FKM 90 back-up rings are used to seal food processing and packaging equipment. The FKM material meets food safety requirements and is able to withstand high-temperature cleaning and sterilization processes.

Aerospace Industry: In the aerospace industry, FKM 90 back-up rings are commonly used in sealing applications in aircraft engines, fuel systems, and hydraulic systems. Due to the high requirements placed on materials in the aerospace sector, the properties of FKM materials enable them to provide reliable sealing performance under harsh environmental conditions.
