An O-ring FKM - 75 Shore A is a specific type of sealing ring made of fluoroelastomer (FKM), with a hardness of 75 Shore A. These O-rings are designed for applications that require a higher degree of firmness and resistance. The fluoroelastomer material offers an excellent combination of chemical resistance and temperature resistance, making them particularly suitable for harsh industrial environments.
Our FKM O-rings - 75 Shore A are available in black, brown, and green. FKM O-rings with a hardness of 75 Shore A are capable of effectively preventing leaks and provide long-lasting performance under extreme conditions, with a temperature range of approximately -15 °C to +200 °C.
The O-ring FKM - 75 Shore A has several key properties that distinguish it from other sealing materials. One of the most notable properties is its excellent temperature resistance, with an operating range of -15 °C to +200 °C, making it suitable for extreme environments. Additionally, this O-ring has excellent chemical resistance.
It can handle 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. Furthermore, the FKM O-ring offers resistance to ozone, weather conditions, and aging, ensuring a long service life even when exposed to harsh environmental factors.
Using an O-ring FKM - 75 Shore A offers several advantages that contribute to its popularity in industrial applications. One of the biggest advantages is its excellent temperature resistance, allowing it to function effectively at both very high and low temperatures. This makes it suitable for various environments, such as engines, turbines, and other equipment operating under extreme temperatures. Additionally, the FKM O-ring offers excellent chemical resistance against a wide range of substances, such as mineral oils, hydrocarbons, and various solvents.
This versatility makes it a reliable choice for sealing in many industrial processes. Moreover, the FKM O-ring has high resistance to ozone, weather conditions, and aging, meaning it lasts a long time without losing quality, even when exposed to harsh environmental factors.
The O-ring FKM - 75 Shore A is used in a wide range of applications due to its robust properties. In the automotive industry, they are often used in engines, fuel systems, and transmissions, where their temperature resistance and chemical resistance are crucial. In the aerospace industry, these O-rings are used in fuel systems and hydraulic systems, where reliability under extreme conditions is essential.
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. Their resistance to ozone and aging also makes them suitable for outdoor use, such as in agricultural equipment and construction machinery.
Although the O-ring FKM - 75 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. In situations where resistance to polar solvents is necessary, FFKM (Perfluoroelastomer) O-rings are a better option due to their excellent chemical resistance.
Additionally, the FKM O-ring is not suitable for use in hot water and overheated steam, making it less suitable for industrial applications involving high temperatures of water or steam. For these applications, EPDM (Ethylene-Propylene-Diene-Monomer) O-rings are often better suited 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 FKM 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 disadvantages, the FKM O-ring remains an excellent choice for many applications due to its versatile and robust properties. For situations where these disadvantages pose a problem, the alternative materials mentioned above can provide a good solution.
