EPDM O-Rings - 90 Shore A

What is an O-ring EPDM - 90 Shore A?

An O-ring EPDM - 90 Shore A is a sealing ring made from Ethylene Propylene Diene Monomer (EPDM) rubber with a hardness of 90 Shore A. These O-rings are suitable for applications that can withstand extreme temperature variations, from -45 °C to +130 °C. Their high hardness provides excellent performance in high-pressure environments where minimal deformation is essential.

An O-ring EPDM - 90 Shore A is highly resistant to aging, ozone, and weather influences, making it ideal for outdoor use and industrial applications. Compared to 70 Shore A EPDM O-rings, which are softer and more flexible, the 90 Shore A variants offer better resistance to mechanical wear and are less prone to permanent deformation under pressure. This makes them the best choice for demanding sealing applications.

Properties of Ethylene Propylene Diene Monomer O-rings

Ethylene Propylene Diene Monomer (EPDM) O-rings are known for their excellent properties, making them suitable for various applications. EPDM O-rings provide exceptional resistance to ozone, UV radiation, and weather influences, making them ideal for outdoor use and industrial environments. Additionally, these O-rings can withstand temperatures from -45 °C to +130 °C, increasing their usability in both cold and hot conditions.

An O-ring EPDM - 90 Shore A also has excellent chemical resistance, particularly against many aqueous and polar substances such as ketones and alcohols. Their good elasticity and flexibility ensure reliable sealing, even under varying pressure and temperature conditions. Furthermore, EPDM is resistant to aging and exhibits little permanent deformation, extending the lifespan of the O-ring EPDM - 90 Shore A. Thanks to these versatile properties, EPDM O-rings are a popular choice in the automotive industry, HVAC systems, and various other industrial applications.

Advantages of an EPDM O-ring - 90 Shore A

An O-ring EPDM - 90 Shore A offers significant advantages for industrial applications. Due to the high hardness of 90 Shore A, these O-rings are ideal for high-pressure applications where minimal deformation is crucial. EPDM O-rings are resistant to hot water and steam, many organic and inorganic acids and bases, silicone oils and greases, ozone, weather conditions, and aging. Moreover, they are resistant to many polar solvents, brine water, and glycol-based brake fluids (special types required).

These O-rings provide excellent performance in demanding environments, but it is important to note that they are not resistant to mineral oil products. The combination of high hardness, broad chemical resistance, and resistance to extreme temperatures makes an O-ring EPDM - 90 Shore A a reliable choice for many sealing applications in various industries.

Applications of EPDM O-rings in 90 Shore A

An O-ring EPDM - 90 Shore A is ideal for a wide range of industrial applications due to their reliability and durability. These O-rings work effectively within a temperature range of -45 °C to +130 °C, making them suitable for both extremely cold and very hot conditions. The 90 Shore A hardness ensures a strong seal with superior resistance to external influences.

These EPDM O-rings are resistant to hot water and steam, various organic and inorganic acids and bases, silicone oils and greases, ozone, weather conditions, aging, many polar solvents, brine water, and glycol-based brake fluids (specific types required). This makes them perfect for applications where chemical resistance and robustness are required.

Thanks to their resilience and long lifespan, an O-ring EPDM - 90 Shore A ensures the smooth operation of equipment in diverse conditions. Although they are not resistant to mineral oil products, they offer unmatched durability and performance for reliable sealing solutions.

Disadvantages of an EPDM 90 O-ring

Despite the many advantages of an O-ring EPDM - 90 Shore A, there are some drawbacks to consider. While they can withstand a wide temperature range from -45 °C to +130 °C and excel in chemical resistance against various substances such as hot steam, organic and inorganic acids, and ozone, EPDM O-rings are not suitable for contact with mineral oil products. This limits their applicability in environments where these oils are prevalent, such as the automotive industry or hydraulic systems that use mineral oil.

Additionally, an O-ring EPDM - 90 Shore A may be subject to permanent deformation when exposed to high pressure and temperatures for extended periods, which can affect long-term performance. Therefore, it is essential to carefully consider the material's compatibility with the specific application conditions to ensure optimal results.
