Products Description

FKM-80-Green-ED-Ring-Seals

FKM 80 green ED ring seals are a type of seal made of fluoro rubber (FKM) material with green color and ED cross-sectional shape. This seal is commonly used in industrial applications that require high-temperature resistance, chemical resistance, and wear resistance.

Advantages

High-temperature resistance

FKM materials can withstand extreme temperatures, often up to 200°C (392°F) or higher, making them suitable for applications involving heat exposure.

Reliability

The geometric design prevents ED seal rings from twisting during installation, ensuring a reliable seal.

Low leakage

ED rings are designed to achieve low leakage rates even when used in low-viscosity media. This feature is critical in applications where liquids must be retained.

Tolerance compensation

The unique shape of ED rings enables them to effectively compensate for manufacturing tolerances.

Customization service

Supports OEM and ODM customization services and can be produced according to customer's specific needs.

Structural design

Special shape: The design of the ED ring allows its use in high-pressure applications while compensating for manufacturing tolerances and ensuring a reliable seal.

Color identification: FKM 80 seals are usually identified by green, making it easy to identify the material type.

Compliance with standards: ED rings comply with DIN 3869, ensuring their suitability and compatibility with a wide range of connectors.

FKM 80 green ED ring seals have a hardness of 80 Shore A and a temperature stability range of -18 to +200°C, which enables them to maintain stable performance under extreme conditions.

ED seal rings comply with DIN3869-1994 standards and are suitable for shaft sealing of equipment such as pumps and cylinders. The pressure can reach 5MPa and the operating temperature can reach 200℃.
