Comprehensive Guide to O-Ring Compression in China
O-rings have become essential components in various industries, serving as reliable sealants that prevent leakage of liquids and gases. Their circular cross-section allows them to fit snugly into grooves, creating a tight seal under pressure. This guide explores the intricacies of O-ring compression, focusing on the manufacturing landscape in China, including key manufacturers, technical features, and types of O-rings.
Understanding O-Ring Compression
O-ring compression refers to the process of fitting an O-ring into a groove where it is compressed between two surfaces. This compression is crucial for creating a seal that can withstand pressure and prevent leaks. The effectiveness of an O-ring depends on several factors, including material, size, and the specific application it is designed for.
Technical Features of O-Rings
When selecting O-rings, it is essential to consider their technical features. Below is a comparison table highlighting the key characteristics of various O-ring materials:
| Material | Temperature Range | Chemical Resistance | Abrasion Resistance | Compression Set | Flexibility | Cost |

| Nitrile (NBR) | -40°C to +120°C | Good | Good | Good | Moderate | Low |
| HNBR | -30°C to +150°C | Excellent | Excellent | Good | High | Moderate |
| Silicone (VMQ) | -60°C to +230°C | Fair | Fair | Excellent | Moderate | Moderate |
| EPDM | -50°C to +150°C | Good | Good | Good | Moderate | Moderate |
| Fluorocarbon (FKM) | -20°C to +200°C | Excellent | Excellent | Poor | High | High |
| FVMQ | -60°C to +225°C | Excellent | Fair | Excellent | High | High |
| Neoprene | -40°C to +120°C | Good | Excellent | Good | Moderate | Moderate |
| FFKM | -20°C to +325°C | Excellent | Excellent | Poor | Very High | Very High |
Types of O-Rings
O-rings come in various types, each designed for specific applications. The following table compares the different types of O-rings:
| Type | Application | Advantages |
|---|---|---|
| O-Ring | Static sealing mainly | Cost-effective, wide range of existing sizes |
| X-Ring (Quad Ring) | Dynamic sealing (rotary and linear) | Four sealing surfaces provide better sealing |
| Y-Ring | Static and dynamic sealing | High over-compression tolerance, low friction |
