Comprehensive Guide to O-Ring Stock in China
O-rings are essential components in various industries, serving as seals to prevent the leakage of fluids and gases. In China, several manufacturers specialize in producing high-quality rubber o-rings, catering to diverse applications. This guide will delve into the technical features, types, and key manufacturers of o-rings, providing a thorough understanding of this critical sealing solution.
Technical Features of O-Rings
O-rings are characterized by their circular cross-section, which allows them to create a reliable seal when compressed between two surfaces. The effectiveness of an o-ring depends on several technical features, including material composition, hardness, and temperature resistance. Below is a comparison table highlighting these features:
| Feature | Description |
|---|---|
| Material | Common materials include NBR, FKM, Silicone, EPDM, and Neoprene. |
| Hardness | Measured in Shore A, typically ranges from 40 to 90, with 70 being standard. |
| Temperature Range | Varies by material; NBR typically withstands -40°C to 120°C, while FKM can go up to 200°C. |
| Chemical Resistance | Different materials offer varying levels of resistance to oils, chemicals, and solvents. |
| Compression Set | Indicates the ability to return to original shape after compression; lower values are better. |
Types of O-Rings
O-rings come in various shapes and sizes, each designed for specific applications. The following table outlines the different types of o-rings available in the market:
| Type | Description |
|---|---|
| Standard O-Ring | Circular cross-section, most commonly used for general sealing applications. |
