What is an O-ring FKM - 80 Shore A

An O-ring FKM - 80 Shore A is a specific type of sealing ring made of fluoroelastomer (FKM), designed with a hardness of 80 Shore A. This means that this O-ring is harder and stiffer than O-rings with a lower hardness, such as 75 Shore A. This higher hardness provides extra mechanical strength and wear resistance, making the O-ring better suited to withstand heavy loads and pressure.

FKM O-rings - 80 Shore A are available in various colors, including black, brown, and green, allowing for visual identification and color coding for diverse applications. For example, an O-ring FKM - 80 Shore A is used to prevent leaks of liquids and gases in demanding industrial and mechanical environments, where reliability and durability are crucial.

Properties of O-ring FKM - 80 Shore A

The O-ring FKM - 80 Shore A stands out due to several unique properties that make it suitable for heavy-duty applications. The increased hardness of 80 Shore A gives this O-ring extra stiffness and wear resistance, which ensures better performance under high pressure and mechanical load. This makes it particularly suitable for applications requiring high mechanical strength.

Additionally, the FKM material offers excellent chemical resistance against a wide range of substances, including mineral oil-based oils and greases, aliphatic and aromatic hydrocarbons, chlorinated hydrocarbons, HFD pressure fluids, silicone oils and greases, non-polar solvents, vegetable and animal oils and fats, and motor fuels.

Moreover, the FKM O-ring has a broad temperature range of -15 °C to +200 °C, making it suitable for use in both low and high temperatures. The O-ring is also resistant to ozone, weather conditions, and aging.

The advantages of FKM O-rings - 80 Shore A

Using an O-ring FKM - 80 Shore A offers several advantages that contribute to its wide applicability in industrial applications. One of the main advantages is the increased hardness of 80 Shore A, which provides improved mechanical strength and wear resistance. This makes the O-ring particularly suitable for applications where high pressure and heavy load occur, such as in hydraulic systems and heavy industrial machinery.

Additionally, an O-ring FKM - 80 Shore A offers excellent chemical resistance against a wide range of substances, making it reliable in various chemical environments. The broad temperature range of -15 °C to +200 °C makes the O-ring suitable for use in extreme temperature conditions, while its resistance to ozone, weather conditions, and aging ensures a longer service life and reduced maintenance costs.

The availability of these O-rings in black, brown, and green provides extra flexibility for color coding and visual identification in various applications.

Applications of an O-ring FKM - 80 Shore A

The O-ring FKM - 80 Shore A is used in a wide range of applications due to its robust properties and increased hardness. In the automotive industry, these O-rings are often used in engines, fuel systems, and transmissions, where their high mechanical strength and temperature resistance are essential. In the aerospace industry, these O-rings are used in fuel systems and hydraulic systems, where reliability under extreme conditions is crucial.

The chemical industry uses FKM O-rings in equipment that comes into contact with aggressive chemicals and solvents, where the chemical resistance of FKM is indispensable. Additionally, FKM O-rings are used in the food and beverage industry, especially in places where equipment needs to be sealed against vegetable and animal fats.

The resistance of FKM O-rings - 80 Shore A to ozone and aging also makes them suitable for outdoor use, such as in agricultural equipment and construction machinery. The availability in black, brown, and green provides additional options for color coding and identification.

Disadvantages of an O-ring FKM - 80 Shore A

Although the O-ring FKM - 80 Shore A offers many advantages, there are also some disadvantages to consider. One major drawback is that it is not resistant to polar solvents, limiting its use in certain chemical environments. For applications where resistance to polar solvents is essential, FFKM (Perfluoroelastomer) O-rings are a better choice due to their excellent chemical resistance.

Additionally, the O-ring is not suitable for use in hot water and overheated steam, making it less suitable for some industrial applications involving high temperatures of water or steam. For these applications, EPDM (Ethylene-Propylene-Diene-Monomer) O-rings are often more suitable due to their excellent heat resistance and steam resistance.

Low molecular weight acids and glycol-based brake fluids are also harmful to the FKM O-ring, preventing its use in systems that work with these fluids. FFKM (Perfluoroelastomer) O-rings, on the other hand, offer superior chemical resistance and can withstand a wide range of acids, bases, and solvents, including glycol-based brake fluids.

Finally, the O-ring is sensitive to degradation by amines and alkalis, further limiting its applicability in certain chemical environments. Aflas (TFE/P) O-rings combine the chemical resistance of FKM with excellent resistance to amines and alkalis, making them suitable for demanding chemical environments.

Despite these drawbacks, the FKM O-ring remains an excellent choice for many applications due to its versatile and robust properties.
