ECO O-Rings

On this page, you will find our standard ECO 70 (Epichlorohydrin) O-rings available in our range. ECO O-rings are commonly used in applications involving oils, fuels, and chemicals due to their excellent resistance to these substances. However, ECO is not recommended for applications involving UV radiation or biological oils and greases. For more information about our ECO O-rings, click here.

What are ECO O-Rings?

ECO O-rings are sealing rings made of Epichlorohydrin Rubber (also known as ECO rubber). This synthetic rubber is renowned for its excellent resistance to oil, fuel, and ozone. These O-rings maintain their elasticity and sealing performance in temperatures ranging from -40°C to 125°C, making them suitable for a wide range of applications.

The key properties of Epichlorohydrin Rubber O-rings include their excellent resistance to oils and fuels, which makes them widely used in automotive applications such as engines, transmissions, and fuel systems. Additionally, they exhibit good resistance to aging and ozone, which extends their lifespan, especially in outdoor applications.

These O-rings are also employed in industrial machinery, hydraulic systems, and water treatment equipment due to their durability and reliable sealing properties in various temperatures and environments.

Advantages of Epichlorohydrin Rubber

ECO O-rings offer several advantages that make them suitable for various sealing applications. A significant benefit is their excellent resistance to oils and fuels, making them commonly used in automotive applications such as engines, transmissions, and fuel systems.

Furthermore, these O-rings maintain their elasticity and sealing performance in temperatures ranging from -40°C to 125°C, making them suitable for both low and moderate temperatures. Epichlorohydrin Rubber O-rings also exhibit good resistance to aging and ozone, extending their lifespan, especially in outdoor applications.

Moreover, O-rings made of this material have good mechanical strength and wear resistance, ensuring durability in use. In summary, the advantages of ECO O-rings include their oil and fuel resistance, temperature resistance, aging resistance, and overall durability, making them a reliable choice for various industrial and automotive sealing applications.

Applications of ECO O-Rings

ECO O-rings are widely used in various industries due to their specific properties. They are particularly applied in automotive sectors, including engines, transmissions, and vehicle fuel systems, due to their excellent resistance to oils and fuels.

Additionally, O-rings made of this material are used in hydraulic systems, industrial machinery, and water treatment equipment because of their durability and reliable sealing properties in various temperatures and environments.

They are also employed in HVAC (heating, ventilation, and air conditioning) equipment, pumps, and valves due to their chemical resistance and mechanical strength. In summary, ECO O-rings are versatile and widely used in various industries where reliable sealing against oils, fuels, and other fluids is required.

Disadvantages of Epichlorohydrin Rubber

Although ECO O-rings offer many advantages, there are also some disadvantages to consider. A key drawback is that this material is less resistant to heat and high temperatures compared to some other rubber types, such as FKM (fluorocarbon). This may make these O-rings unsuitable for applications with extremely high temperatures.

Additionally, these O-rings have a narrower temperature range compared to silicone rubber or FKM, with a maximum continuous use temperature of approximately 125°C. This can limit their usability in applications with higher temperatures.

Lastly, ECO O-rings may be sensitive to certain chemicals and solvents, which could make them unsuitable for all chemically aggressive environments. It is important to check the compatibility of this material with specific media before application.
