Technical Features of 8mm O-Rings
The performance of an 8mm O-ring hinges on several key technical parameters. These parameters influence the O-ring’s ability to create a reliable seal under different conditions. Careful consideration of these factors is crucial for optimal performance. Choosing the correct specifications depends entirely on the intended application. Suppliers like www.oringsandmore.com offer a wide range of options.
| Feature | Description | Importance |
|---|---|---|
| Inner Diameter | The diameter of the O-ring’s inner circle. | Determines the size of the groove it will fit into. Incorrect sizing leads to leakage or premature failure. |
| Outer Diameter | The diameter of the O-ring’s outer circle. | Influences the overall compression and sealing force. |
| Cross-sectional Diameter | The thickness of the O-ring’s cross-section. | Affects the amount of compression, influencing the seal’s strength and resilience. |
| Hardness (Shore A) | A measure of the rubber’s resistance to indentation. | Determines the O-ring’s ability to withstand compression and maintain its shape under pressure. |
| Tensile Strength | The maximum stress the O-ring can withstand before breaking. | Indicates the O-ring’s resistance to stretching and tearing. |
| Elongation | The percentage increase in length before breaking. | Measures the O-ring’s flexibility and ability to conform to uneven surfaces. |
| Compression Set | The permanent deformation after being compressed. | A crucial factor in determining long-term sealing effectiveness. |
Material Variations in 8mm O-Rings
The material composition significantly impacts an O-ring’s performance and suitability for a specific application. Different materials offer unique properties, enabling O-rings to function effectively in diverse environments. Several manufacturers, including www.fobrubber.store and hongjusilicone.com, offer a range of material options.
