Comprehensive Guide to O-Ring Gaskets
O-rings are essential components in various industries, serving as reliable sealing solutions for preventing leaks in mechanical systems. These circular seals, typically made from elastomeric materials, are designed to fit into a groove and create a tight seal when compressed. In this guide, we will explore the different types of O-rings, their technical features, and the leading manufacturers in China, including Savvy Rubber, Kaxite Sealing, Yoson, Hongju, and Yuefeng Seal.
Understanding O-Rings
O-rings are widely used in hydraulic and pneumatic systems, as well as in automotive, aerospace, and industrial applications. Their primary function is to prevent the escape of fluids or gases, ensuring the efficient operation of machinery. The design of O-rings allows them to accommodate various pressures and temperatures, making them versatile for different applications.
Technical Features of O-Rings
The effectiveness of O-rings is determined by several technical features, including material composition, hardness, temperature resistance, and size. Below is a comparison table highlighting these features:
| Feature | Description |
|---|---|
| Material | Common materials include NBR, FKM, Silicone, EPDM, and HNBR. |
| Hardness | Measured in Shore A, typically ranges from 40 to 90, with 70 being common. |
| Temperature Range | Varies by material; NBR (-40°C to 120°C), FKM (-20°C to 200°C), Silicone (-70°C to 220°C). |
| Size | Specified by ID (inside diameter), OD (outside diameter), and CS (cross-section). |
| Color | Available in various colors for identification; common colors include black, green, and red. |
Types of O-Rings
O-rings come in various types, each designed for specific applications. The following table outlines the different types of O-rings and their characteristics:
| Type | Description |
|---|---|
| Standard O-Rings | Commonly used in general applications; available in various sizes and materials. |
| Encapsulated O-Rings | Feature a core material (like silicone) surrounded by a fluoropolymer for chemical resistance. |
| Backup Rings | Used in conjunction with O-rings to prevent extrusion in high-pressure applications. |
| X-Rings | Also known as quad rings; provide a better sealing surface and are less prone to twisting. |
| Custom O-Rings | Tailored to specific dimensions and materials based on customer requirements. |
