Comprehensive Guide to Flat Silicone O-Rings
Introduction
Hongju is one of the leading custom O-ring manufacturers and wholesalers in China. We produce high-quality silicone rubber O-rings and high-temperature O-ring seals for engines, pumps, cylinders, connectors, valves, and more. With a vast inventory of standard sizes and the capability to create custom O-rings, we cater to diverse sealing needs.
Understanding O-Rings
O-rings are circular seals made from elastomeric materials, primarily used to prevent the leakage of fluids or gases. Their design allows them to fit snugly into grooves, creating a seal when compressed between two surfaces. This simple yet effective design makes O-rings a staple in various industries, including automotive, aerospace, and manufacturing.
Technical Features of O-Rings
When selecting O-rings, understanding their technical features is crucial. Below is a comparison table highlighting key technical specifications:
| Feature | Description |
|---|---|
| Material | Typically made from silicone, nitrile, or fluorocarbon rubber. |
| Temperature Range | Silicone O-rings can withstand temperatures from -60°C to 200°C. |
| Hardness | Measured in Shore A, typically ranges from 30A to 90A. |
| Chemical Resistance | Varies by material; silicone offers good resistance to water and ozone. |
| Compression Set | Ability to return to original shape after compression; lower is better. |
| Tensile Strength | Indicates the maximum stress a material can withstand while being stretched. |
Types of O-Rings
O-rings come in various types, each suited for specific applications. The following table outlines the differences between common O-ring types:
| Type | Description |
|---|---|
| Standard O-Rings | Commonly used in various applications; available in many sizes. |
| Custom O-Rings | Tailored to specific dimensions and materials based on client requirements. |
| High-Temperature O-Rings | Designed to withstand extreme temperatures, ideal for engines and pumps. |
