Fluorocarbon (FKM)O-Rings
1. Material properties
Chemical stability
Fluorocarbon (FKM) O-Rings are made of fluororubber (FKM), which has excellent chemical stability. It can withstand corrosion from a variety of chemicals, including strong acids, strong alkalis, organic solvents, etc. In the chemical and pharmaceutical industries, various corrosive chemicals are often exposed. FKM O-Rings can maintain good sealing performance in such harsh chemical environments to ensure the safe operation of equipment.
High temperature resistance
FKM material has excellent high temperature resistance. It can work normally in a higher temperature range, generally able to withstand a temperature range of -20℃ to 200℃, and some specially formulated FKM O-Rings can even withstand higher temperatures. This makes it perform well in sealing applications in high temperature environments such as automotive engines and aerospace engines.
2. Product structure and sealing principle
Simple and efficient structure
Fluorocarbon (FKM) O-Rings have a simple and effective structure, usually in a ring shape. Its circular structure can fit tightly with the sealing surface after being installed in the sealing groove.
Sealing principle
When subjected to pressure, the O-Ring will deform elastically and fill the tiny gap between the sealing surfaces. This elastic deformation ability enables it to maintain the sealing effect under different pressure conditions, whether it is a high-pressure or low-pressure environment, it can effectively prevent the leakage of fluids or gases.
3. Application advantages
Wide applicability
Due to its chemical stability and high temperature resistance, Fluorocarbon (FKM) O-Rings are widely used in many industries such as automobiles, aerospace, petrochemicals, electronics and electrical appliances. It plays a key sealing role in the fuel system and hydraulic system of automobile engines, the lubrication system and hydraulic pipelines of aerospace engines, etc.
Reliable sealing performance
Fluorocarbon (FKM) O-Rings can provide reliable long-term sealing effects and reduce the maintenance cost of equipment. Its stability in different working environments ensures the normal operation of the equipment and improves the overall performance and safety of the equipment.
