An O-ring EPDM - 80 Shore A is a robust sealing ring made from EPDM rubber with excellent resistance to ozone, UV radiation, and various weather conditions, making it ideal for outdoor applications. They have high wear resistance and perform well under mechanical stress, making them suitable for demanding industrial applications. Despite sensitivity to extreme temperatures and unsuitability for mineral oil products, they remain a reliable choice for durable and effective seals. Also check the EPDM material page for the key EPDM properties, such as resistance to water, steam and weathering, and an overview of all EPDM hardness grades and applications.
An O-ring EPDM - 80 Shore A is a robust sealing ring made of ethylene-propylene-diene-monomer (EPDM) rubber with a hardness of 80 Shore A. This O-ring offers excellent resistance to ozone, UV radiation, and various weather conditions, making it ideal for outdoor applications.
Compared to an O-ring EPDM - 70 Shore A, the 80 Shore A variant provides higher wear resistance and can better handle higher mechanical loads, making it perfect for demanding industrial applications. However, an O-ring EPDM - 70 Shore A has better flexibility and sealing capacity at lower pressures.
Therefore, the 70 Shore A variant is ideal for applications requiring a softer seal and more adaptability. Choose the right EPDM O-ring based on the specific requirements of your application to ensure optimal performance and durability.
An O-ring EPDM - 80 Shore A is a high-quality sealing solution known for its robust properties. Made from ethylene-propylene-diene-monomer (EPDM) rubber with a hardness of 80 Shore A, this O-ring offers excellent resistance to ozone, UV radiation, and various weather conditions, making it ideal for outdoor applications.
Additionally, the 80 Shore A hardness provides higher wear resistance and better performance under higher mechanical loads, making it suitable for demanding industrial applications. These O-rings are also resistant to a wide range of chemicals, including hot water, steam, brake fluids, and various acids and bases.
Due to the high hardness, an O-ring EPDM - 80 Shore A offers less compression and deformation, resulting in longer lifespan and reliable sealing in extreme conditions. These properties make EPDM O-rings - 80 Shore A a popular choice for heavy industrial applications where durability and performance are essential.
An O-ring EPDM - 80 Shore A offers numerous benefits for various industrial applications. This O-ring is highly resistant to hot water and steam, making it ideal for use in heating and steam systems. Additionally, it provides excellent resistance to many organic and inorganic acids and bases, as well as silicone oils and greases, making it versatile in chemical and industrial environments.
Thanks to high resistance to ozone, weather conditions, and aging, EPDM O-rings - 80 Shore A are perfect for outdoor applications. They perform well in diverse climatic conditions and maintain their integrity over long periods. These O-rings are also resistant to many polar solvents and brine washes, adding to their versatility.
Moreover, they can withstand glycol-based brake fluids, although special grades are required. These robust properties make O-ring EPDM - 80 Shore A a reliable choice for long-lasting, effective seals in various demanding applications.
An O-ring EPDM - 80 Shore A is versatile and suitable for various applications due to its excellent resistance to hot water and steam, many organic and inorganic acids and bases, and silicone oils and greases. These O-rings perform excellently in outdoor environments, thanks to their resistance to ozone, weather conditions, and aging. They are ideal for HVAC systems, water treatment plants, and sanitary applications.
EPDM O-rings are also resistant to many polar solvents and brine washes, making them suitable for chemical and industrial processes. While they withstand glycol-based brake fluids (special grades required), they are not suitable for applications with mineral oil products, strong acids, and bases.
Additionally, an O-ring EPDM - 80 Shore A offers a wide temperature range, from -20°C to +130°C for standard types, and up to +180°C for specialized types. Their excellent chemical and aging resistance makes them reliable for SIP and CIP cleaning processes and use with vegetable oils, alcohols, ketones, and engine coolants.
While an O-ring EPDM - 80 Shore A offers many advantages, there are some drawbacks to consider. One significant drawback is their unsuitability for applications containing mineral oil products. This makes them less suitable for use in the oil and gas industry.
Additionally, EPDM O-rings have limitations at extreme temperatures. While they withstand temperatures up to +130°C for SC types and up to +180°C for PC types, they can lose elasticity and degrade at temperatures above these limits. Also, at very low temperatures down to -20°C or -55°C, depending on the composition, their flexibility may decrease, negatively affecting their sealing capacity.
Moreover, an O-ring EPDM - 80 Shore A is not resistant to strong acids and bases, limiting their applicability in certain chemical environments. Despite their excellent resistance to hot water, steam, ozone, UV, and various chemicals, it is important to consider the limitations of EPDM O-rings in 80 Shore A when selecting the right sealing material.
