What is an O-ring EPDM - 70 Shore A?

An O-ring EPDM - 70 Shore A is a high-quality sealing ring made from ethylene-propylene-diene-monomer (EPDM) rubber with a hardness of 70 Shore A. This O-ring is particularly suitable for applications where resistance to ozone, UV radiation, and various weather conditions is essential. EPDM 70 O-rings are also resistant to a wide range of chemicals, such as water, steam, and certain acids and bases, making them ideal for industrial and automotive applications.

With a hardness of 70 Shore A, an O-ring EPDM offers a good balance between flexibility and durability, providing effective sealing and long-lasting performance. Thanks to its versatile properties, an O-ring EPDM - 70 Shore A is often used in hydraulic and pneumatic systems, as well as in construction for waterproof seals.

Properties of an EPDM O-ring in 70 Shore A

Properties of an O-ring EPDM - 70 Shore A include excellent resistance to ozone, UV radiation, and various weather conditions, making it ideal for outdoor applications. With a hardness of 70 Shore A, it offers an optimal balance between flexibility and rigidity.

Compared to an EPDM 80 Shore A O-ring, which is harder, the 70 Shore A O-ring offers better flexibility and can seal better at lower pressure. On the other hand, an EPDM 80 Shore A O-ring provides higher wear resistance and is suitable for applications with higher mechanical loads.

Compared to an EPDM 60 Shore A O-ring, which is softer, the 70 Shore A O-ring offers better shape retention and durability. However, an EPDM 60 Shore A O-ring is better suited for applications requiring more compression and adaptability.

Overall, an O-ring EPDM - 70 Shore A provides an excellent middle ground between the properties of the softer and harder variants.

Advantages of an EPDM 70 O-ring

The advantages of an O-ring EPDM - 70 Shore A are numerous, making it a popular choice for various sealing applications. Thanks to its excellent resistance to ozone, UV radiation, and weather conditions, it is ideal for outdoor applications. An EPDM O-ring also offers excellent chemical resistance, especially to water, steam, and many acids and bases, making it suitable for industrial environments.

The hardness of 70 Shore A ensures an optimal balance between flexibility and rigidity, providing effective sealing and durability. Additionally, an O-ring EPDM - 70 Shore A retains its elastic properties at extreme temperatures, from -40°C to +120°C.

This versatility makes an EPDM 70 O-ring suitable for use in the automotive sector, construction, hydraulic and pneumatic systems, and household appliances. The durability and adaptability ensure reliable performance in various applications.

Applications of an O-ring EPDM - 70 Shore A

The applications of an O-ring EPDM - 70 Shore A are versatile due to its excellent resistance to ozone, UV radiation, and various weather conditions.

It is widely used in the automotive sector for seals in braking systems, cooling systems, and air conditioners. In the construction sector, it is essential for waterproof seals in roofs, facades, and windows. Industrial applications include use in hydraulic and pneumatic systems, where it reliably seals under varying pressure and temperature conditions.

An O-ring EPDM - 70 Shore A is also ideal for use in household appliances, irrigation systems, and plumbing due to its excellent chemical resistance to water, steam, and many acids and bases. Thanks to its 70 Shore A hardness, it offers a perfect balance between flexibility and rigidity, resulting in durable and effective seals in various applications.

Disadvantages of an EPDM O-ring in 70 Shore A

The disadvantages of an O-ring EPDM - 70 Shore A are important to consider when choosing sealing materials. Although it is highly resistant to ozone, UV radiation, and weather conditions, it has limitations in chemical resistance. An EPDM O-ring is not resistant to fuels, hydrocarbons, oils, and greases, making it less suitable for applications involving contact with these substances.

Additionally, an O-ring EPDM - 70 Shore A may lose its elastic properties at temperatures above 120°C, which can affect performance in high-temperature environments. While the hardness of 70 Shore A offers a good balance between flexibility and rigidity, this material may be less suitable for very low-pressure applications where a softer O-ring, such as 60 Shore A, would perform better.

These disadvantages should be carefully weighed against the benefits when selecting the appropriate sealing material.

Specifications of an O-ring EPDM - 70 Shore A

The O-ring EPDM - 70 Shore A, with material number 127019001, has a hardness of 70 ±5 Shore A, a tensile strength of 10.9 MPa, and an elongation at break of 282%. The density is 1.19 ±0.03 g/cm³. The compression set after 22 hours at 125°C is 38%. The tear resistance is 49 N/mm.

At low temperatures, the material shows no cracking after 3 minutes at -40°C and has a TR10 value of -41°C. After aging at 125°C in air, the properties change: hardness increases by +4 points, tensile strength increases by +14%, and elongation at break decreases by -24%. In water, the volume increases by +2%.

The data for this O-ring EPDM - 70 Shore A are based on tests according to modern laboratory standards and may vary in final products.
