The o-ring is mainly used for static gap sealing of fluids (such as water,oil, air chemical solvents, chemicals,etc.). The long-term using in the temperature between -60 and 220 degrees,it depends on the material, and the static pressure is less than 20Mpa. Sometimes used for dyamic, dynamic pressures less than 5 MPa, and also used for the semiconductor vacuum seals.

FKM O-rings are sealing components made from fluorocarbon rubber (FKM), which is known for its excellent resistance to high temperatures, chemicals, and oils. FKM, commonly recognized by brand names such as Viton, is a synthetic rubber that is widely used in various industries due to its superior properties.

Key Characteristics of FKM O-Rings

1. Temperature Resistance: FKM O-rings can typically withstand temperatures ranging from -20°C to +200°C (-4°F to +392°F), and some formulations can handle even higher temperatures.

2. Chemical Resistance: They exhibit outstanding resistance to a wide variety of chemicals, including fuels, oils, solvents, and many aggressive chemicals, making them suitable for use in automotive, aerospace, and industrial applications.

3. Durability: FKM materials are known for their excellent aging properties, providing long service life even in harsh environments.

4. Low Compression Set: FKM O-rings maintain their shape and sealing ability over time, even under compression.

5. Versatility: They can be used in static and dynamic applications, although careful consideration should be given to the specific application requirements.

Applications

● Automotive: Used in fuel systems, oil seals, and other components that require resistance to fuels and high temperatures.

● Aerospace: Suitable for seals in aircraft engines and fuel systems.

● Industrial Equipment: Commonly found in hydraulic systems, pumps, and valves that operate with aggressive fluids.

● Chemical Processing: Used in seals and gaskets where exposure to harsh chemicals is expected.

Considerations

When selecting FKM O-rings, it's essential to consider factors such as the specific chemicals involved, the operating temperature range, and the pressure conditions of the application. Proper sizing and installation are also crucial to ensure effective sealing and prevent leaks.
