A Comprehensive Guide to Parker O-Ring Suppliers in China
Finding reliable Parker O-ring suppliers in China is crucial for businesses needing high-quality sealing solutions. Parker Hannifin is a global leader in motion and control technologies, and their O-rings are known for their precision and performance. This guide will explore the landscape of Parker O-ring suppliers in China, delve into their technical aspects, and highlight the differences between various types.
Understanding Parker O-Rings
Parker O-rings are elastomeric seals with a toroidal (doughnut) shape. They are used extensively in various industries for static and dynamic sealing applications. Their effectiveness stems from their ability to create a tight seal by deforming under pressure, preventing leakage of fluids or gases. The material composition significantly impacts performance characteristics, as we will see later. Several Chinese companies, such as those found on www.jiuhongseal.com and m.king-rubber.com, specialize in supplying these critical components.
Technical Features of Parker O-Rings
The performance of a Parker O-ring depends heavily on its material properties and dimensions. Key technical features to consider include material type, hardness, temperature range, and pressure resistance. Let’s examine these in detail:
| Feature | Description |
|---|---|
| Material Type | Common materials include Nitrile (NBR), EPDM, FKM (Viton), and Silicone. Each offers different chemical resistance and temperature capabilities. |
| Hardness (Shore A) | Measures the material’s resistance to indentation. Typical ranges are 60-90 Shore A. |
| Temperature Range | The operational temperature range varies significantly depending on the material. |
| Pressure Resistance | The maximum pressure an O-ring can withstand before failure. This depends on the material, size, and application. |
| Size | O-rings are specified by their inside diameter (ID), outside diameter (OD), and cross-section (CS). Standardization exists (AS568, JIS, etc.). |
Companies like www.parkerseal.net and www.espint.com often offer detailed specifications and selection guides for their Parker O-ring offerings.
Different Types of Parker O-Rings
Parker O-rings are available in a wide variety of materials to suit different applications. The choice of material depends on factors such as the fluid being sealed, the temperature range, and the required durability. Here’s a comparison:
| Material | Chemical Resistance | Temperature Range (°C) | Applications |
|---|---|---|---|
| NBR (Nitrile) | Oils, fuels, water, many chemicals | -30 to +100 | General purpose, hydraulic systems, pneumatic systems |
| EPDM | Water, steam, many chemicals | -40 to +150 | Automotive, industrial applications, high-temperature applications |
| FKM (Viton) | Oils, fuels, many chemicals | -20 to +200 | High-temperature applications, aggressive chemicals |
| Silicone | Many chemicals, ozone | -50 to +200 | High-temperature applications, food and beverage applications |
Choosing the right material is critical to ensuring the O-ring’s longevity and effectiveness. TVH, as a distributor (www.tvh.com), offers a range of Parker O-rings and can advise on material selection.
Selecting a Parker O-Ring Supplier in China
When choosing a supplier, consider factors such as their experience, quality control measures, certifications, and lead times. Ensure they can provide the required material, size, and quantity. Compare prices from multiple suppliers to find the best value. Checking reviews and testimonials can help assess a supplier’s reliability.
