Project details

EPDM O-ring seal is a common sealing material widely used in various occasions, including brake systems. Here are some common EPDM O-ring specifications:

Inner diameter: 1.5mm to 60mm;

Outer diameter: 3mm to 100mm;

Wire diameter: 1mm to 6mm;

Wall thickness: 0.7mm to 5mm;

Hardness: Shore hardness A 30-90 degrees;

Temperature range: -40 ℃ to+120 ℃;

Oil resistance: It has good oil resistance and can be used in most mineral oils, brake fluids, and lubricants;

Aging resistance: EPDM rubber has good aging resistance and can be used in natural environments for several years;

Compression permanent deformation: Low compression permanent deformation, suitable for long-term sealing.

It should be noted that specific specifications and performance parameters may vary depending on different manufacturers and application scenarios. In practical use, it is also necessary to select and customize according to specific requirements and conditions.
