An O rings are round rubber seals/rubber rings/sealing gaskets that fits into a groove and is compressed between two or more components to create a reliable seal and prevent leakage.
O Ring Technical Data
1. Dimensions
Inner Diameter (ID): Standard metric and inch sizes available.
Cross-Section (CS): Range of thicknesses to fit different grooves and sealing requirements
Tolerance: Conforms to ISO 3601 / AS568 standards
2. Materials & Compounds
- NBR (Nitrile Rubber): Good resistance to oils, fuels, and water; temperature range: -40°C to 100°C
- EPDM (Ethylene Propylene): Excellent resistance to heat, steam, and chemicals; temperature range: -50°C to 150°C
- FKM / Viton: High temperature and chemical resistance; temperature range: -20°C to 200°C
- Silicone: Excellent flexibility at low temperatures; temperature range: -60°C to 200°C
- PU (Polyurethane): High wear resistance; temperature range: -30°C to 90°C
3. Application
- Hydraulic systems
- Pneumatic systems
- Static sealing (Like flanges, covers)
- Low-pressure dynamic sealing (Like rods, pistons)
4. Physical Properties
