Technical Features of O-Rings
O-rings are designed to create a seal between two surfaces, preventing the escape of fluids or gases. Their effectiveness depends on several technical features, including material composition, hardness, and temperature resistance. Below is a comparison table of the key technical features of O-rings:
| Feature | Description |
|---|---|
| Material | Common materials include Nitrile (NBR), Fluorocarbon (FKM), EPDM, and Silicone. |
| Hardness | Measured in Shore A, typically ranging from 30 to 90, affecting flexibility and sealing capability. |
| Temperature Range | Varies by material; NBR: -40°C to +120°C, FKM: -20°C to +200°C, EPDM: -50°C to +150°C. |
| Compression Set | Ability to return to original shape after compression; lower values indicate better performance. |
| Chemical Resistance | Varies by material; FKM offers excellent resistance to oils and fuels, while EPDM is good for water and steam. |
| Durability | O-rings are designed for long-term use, withstanding wear and environmental factors. |
Types of O-Rings
O-rings can be categorized based on their design and application. Understanding the differences between these types is crucial for selecting the right O-ring for specific needs. The following table outlines the various types of O-rings:
| Type | Description |
|---|---|
| Standard O-Ring | Commonly used for static sealing applications; available in various sizes. |
| X-Ring (Quad Ring) | Features four sealing surfaces, providing better sealing performance for dynamic applications. |
| Y-Ring | Suitable for both static and dynamic sealing; offers high over-compression tolerance. |
| Custom O-Ring | Tailored to specific requirements, including size, material, and hardness. |
| Spliced O-Ring | Made from O-ring cord; allows for on-site customization and emergency repairs. |
| Metric O-Ring | Designed to meet metric standards; commonly used in European applications. |
| Imperial O-Ring | Follows imperial measurements; widely used in North American industries. |
