Technical Features of 38mm O-Rings
O-rings are characterized by their circular cross-section, which allows them to create a seal when compressed between two surfaces. The following table outlines the key technical features of O-rings:
| Feature | Description |
|---|---|
| Material | Common materials include NBR, FKM, EPDM, and silicone, each with unique properties. |
| Temperature Range | Varies by material; typically from -60°C to +250°C for specialized compounds. |
| Hardness | Measured in Shore A; ranges from 40 to 90, depending on application requirements. |
| Chemical Resistance | Varies by material; FKM offers excellent resistance to oils and fuels, while EPDM is good for water. |
| Compression Set | Indicates the ability to return to original shape after compression; lower values are preferable. |
| Tensile Strength | Indicates the maximum stress the material can withstand; higher values indicate better durability. |
Types of O-Rings
O-rings come in various types, each designed for specific applications and environments. The following table compares the different types of O-rings:
| Type | Description | Advantages |
|---|---|---|
| Standard O-Ring | Basic circular cross-section for general sealing applications. | Cost-effective and widely available. |
| X-Ring (Quad Ring) | Features four sealing surfaces for improved performance. | Better sealing performance and lower friction compared to standard O-rings. |
| Y-Ring | Designed for both static and dynamic sealing applications. | High over-compression tolerance and low friction. |
| Encapsulated O-Ring | O-ring coated with a layer of another material for enhanced properties. | Excellent chemical resistance and reduced friction. |
| Backup Ring | Used in conjunction with O-rings to prevent extrusion in high-pressure applications. | Increases the lifespan of O-rings in dynamic applications. |
