Different Types of 14 O-Rings
While the core function remains the same, variations in size, shape, and material lead to a wide array of O-ring types. Savvyrubber.com showcases a comprehensive catalog of these variations. The table below highlights some key differences:
| O-Ring Type | Shape | Material Options | Typical Applications | Advantages | Disadvantages |
|---|---|---|---|---|---|
| Standard | Toroidal | NBR, Viton, Silicone, EPDM, etc. | General sealing | Wide availability, cost-effective | Limited chemical/temperature resistance in some materials |
| Encapsulated | Toroidal | PTFE encapsulated silicone, etc. | Harsh chemical environments | Excellent chemical resistance, good elasticity | Higher cost |
| X-Ring | Quadruple-lip | Various elastomers | High-pressure, dynamic applications | Superior sealing performance, longer lifespan | More complex design, higher cost |
| Backup Ring | Various | Typically PTFE, other materials for specific needs | Added protection for primary seals, improved resilience | Enhanced seal integrity, prevents extrusion | Increased complexity and cost |
| Square | Square | Various elastomers | Specific applications requiring square sealing surface | Enhanced sealing in certain geometries | Less common, potentially more expensive |
| Custom | Varies | Wide range of materials and designs | Applications with unique requirements | Precise fit, optimized performance | Higher initial cost, longer lead times |
Understanding these differences allows for the selection of the most appropriate O-ring for a given application. www.zhonggaoseals.com provides a broad selection of O-ring types.
