Comprehensive Guide to 65mm Rubber O-Rings in China
When it comes to sealing solutions, rubber O-rings play a crucial role in various industries, including automotive, aerospace, and medical applications. Among the many sizes available, the 65mm rubber O-ring is particularly popular due to its versatility and effectiveness in preventing leaks. This guide will delve into the manufacturing technology, quality considerations, and sourcing tips for 65mm rubber O-rings in China, highlighting key manufacturers and their offerings.
Understanding Rubber O-Rings
Rubber O-rings are circular seals with a cross-section shaped like the letter “O.” They are designed to fit into a groove and create a seal between two or more parts, preventing the escape of fluids or gases. The effectiveness of an O-ring depends on its material, size, and the application it is used for.
Technical Features of Rubber O-Rings
The following table summarizes the key technical features of rubber O-rings:
| Feature | Description |
|---|---|
| Material | Common materials include NBR, FKM (Viton), EPDM, and silicone. |
| Temperature Range | Varies by material; typically from -60°C to 200°C. |
| Pressure Resistance | Capable of withstanding high pressures, depending on the material and design. |
| Chemical Resistance | Varies by material; NBR is good for oils, while FKM is excellent for chemicals. |
| Size Tolerance | Standard tolerances are ±0.01mm for O-rings, ensuring a precise fit. |
Types of Rubber O-Rings
Rubber O-rings come in various types, each suited for specific applications. The following table outlines the differences between common types of O-rings:
| Type | Description |
|---|---|
| Standard O-Rings | Basic circular seals used in general applications. |
| Encapsulated O-Rings | O-rings coated with a layer of Teflon or other materials for enhanced chemical resistance. |
| Backup Rings | Used in conjunction with O-rings to prevent extrusion in high-pressure applications. |
| X-Rings | Four-lobed seals that provide a larger sealing surface and reduced friction. |
| Custom O-Rings | Tailored to specific dimensions and materials based on client requirements. |
