What is an O-ring FKM - 90 Shore A

An O-ring FKM - 90 Shore A is a specific type of sealing ring made of fluoroelastomer (FKM) with a hardness of 90 Shore A. This makes this O-ring significantly harder and stiffer than other FKM O-rings with lower hardness, such as 75 Shore A. The increased hardness provides extra mechanical strength and wear resistance, making the O-ring better suited to withstand heavy loads and high pressure.

These properties make an O-ring FKM - 90 Shore A particularly suitable for industrial applications where high performance and durability are required. O-rings with this hardness are designed to effectively prevent leaks of liquids and gases in demanding environments. They are a reliable choice for applications requiring extreme pressure and wear resistance.

Properties of an FKM O-ring in 90 Shore A

The O-ring FKM - 90 Shore A stands out due to several unique properties that make it particularly suitable for heavy-duty applications. The hardness of 90 Shore A gives this O-ring a high degree of stiffness and wear resistance, ensuring excellent performance under high pressure and mechanical load.

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, an O-ring FKM - 90 Shore A has a broad temperature range of -15 °C to +200 °C, making it suitable for both low and high temperatures. The O-ring is also resistant to ozone, weather conditions, and aging, ensuring a longer service life.

The advantages of an FKM 90 Shore A O-ring

Using an O-ring FKM - 90 Shore A offers several advantages that contribute to its popularity in demanding industrial applications. One of the main advantages is the increased hardness of 90 Shore A, which provides improved mechanical strength and wear resistance. This makes the O-ring ideal for applications where high pressure and heavy loads occur, such as hydraulic systems, pumps, and compressors. The excellent chemical resistance of the FKM material ensures the O-ring remains reliable in contact with a wide range of chemical substances.

The broad temperature range of -15 °C to +200 °C makes the O-ring suitable for use in extreme temperature conditions, while the resistance to ozone, weather conditions, and aging contributes to a longer service life and reduced maintenance costs. The combination of these properties makes the FKM - 90 Shore A O-ring a durable and cost-effective choice for many heavy industrial applications.

Applications of FKM O-rings - 90 Shore A

The O-ring FKM - 90 Shore A is used in a wide range of applications due to its robust properties and high 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 - 90 Shore A are used in the oil and gas industry, especially in applications where high pressure and heavy loads are involved. Their resistance to ozone and aging also makes them suitable for outdoor use, such as in agricultural equipment and construction machinery.

Disadvantages of an O-ring FKM - 90 Shore A

Although the O-ring FKM - 90 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. 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.

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. Finally, the O-ring is sensitive to degradation by amines and alkalis, further limiting its applicability in certain chemical environments. Despite these disadvantages, the O-ring FKM - 90 Shore A remains an excellent choice for many applications due to its versatile and robust properties.
