The Comprehensive Guide to 009 O-Rings in China
O-rings, simple yet crucial components, are ubiquitous in various industries. The ‘009 O-ring’, identified by its size designation, holds a significant place in the market. This guide delves into the world of 009 O-rings, focusing specifically on their presence and characteristics within the Chinese manufacturing landscape. We will explore their technical features, different types, and common applications. Sources for this information include major industrial suppliers like MSC Industrial Supply (www.mscdirect.com), online marketplaces such as eBay (www.ebay.ca), and specialized Chinese manufacturers such as those found on www.rubberplasticparts.com, www.brotherrubber.com and www.dmsseals.com.
Understanding 009 O-Ring Specifications
The ‘009’ designation refers to a specific size according to industry standards, typically AS568. This standard defines the inner diameter (ID), outer diameter (OD), and cross-sectional diameter (CS) of the O-ring. While the exact dimensions can vary slightly depending on the manufacturer, the 009 O-ring generally has a small ID and a thin cross-section. This makes it suitable for applications requiring a compact seal. Many online retailers and industrial suppliers, such as www.mscdirect.com, list these specifications clearly for their products.
Technical Features of 009 O-Rings
Different materials offer varying performance characteristics. The choice of material depends heavily on the specific application and environmental conditions. Common materials include Buna-N (Nitrile), Silicone, and Viton (FKM). Chinese manufacturers like those on www.rubberplasticparts.com offer a wide range of material options for custom orders.
| Material | Temperature Range (°C) | Chemical Resistance | Compression Set | Cost |
|---|---|---|---|---|
| Buna-N (Nitrile) | -30 to +100 | Oils, fuels, water | Moderate | Low |
| Silicone | -60 to +200 | Many chemicals, ozone | High | Moderate |
| Viton (FKM) | -20 to +250 | Wide range of chemicals | Low | High |
Types of 009 O-Rings and Their Differences
Beyond material, variations exist in shape and design. While the standard 009 O-ring is a simple toroidal shape, other specialized designs cater to unique sealing needs. These variations are frequently highlighted by Chinese manufacturers like those listed on www.brotherrubber.com.
| Type | Description | Applications | Advantages | Disadvantages |
|---|---|---|---|---|
| Standard O-ring | The basic toroidal shape. | General sealing applications. | Simple, cost-effective, widely available. | May not be suitable for extreme conditions. |
| Square O-ring | Rectangular cross-section, providing higher sealing force. | High-pressure applications. | Increased sealing capacity, better resistance to extrusion. | More expensive, potentially more difficult to install. |
| Back-up Rings | Used in conjunction with standard O-rings to protect against extrusion. | Applications with high pressure or extrusion risk. | Prevents O-ring extrusion, extends O-ring lifespan. | Adds complexity to the assembly. |
Chinese 009 O-Ring Manufacturers and Suppliers
China is a major producer of O-rings, offering a vast selection of standard and custom-made 009 O-rings. Suppliers such as those listed on www.dmsseals.com often offer a wide range of materials and sizes, along with customization options to meet specific requirements. Online marketplaces like www.ebay.ca provide access to a broader selection of Chinese manufacturers and distributors, though quality and reliability can vary.
Conclusion
The 009 O-ring, a small but vital component, plays a crucial role in countless applications.
