Parker Hannifin O-Rings in China: A Comprehensive Guide
Parker Hannifin, a global leader in motion and control technologies, offers a wide range of O-rings crucial for sealing applications across various industries in China. This guide delves into the world of Parker Hannifin O-rings, exploring their technical specifications, diverse types, and applications within the Chinese market. Information sourced from official Parker websites like www.parker.com and crossref.parker.com, along with distributor sites such as www.ostbridge-tech.com and community.b-china.cn, contributes to this comprehensive overview.
Understanding Parker Hannifin O-Rings
Parker Hannifin O-rings are elastomeric seals with a toroidal (donut) shape. They are used to create a leak-proof seal between two mating surfaces. Their effectiveness stems from their ability to deform under compression, filling the gap between the surfaces. Parker’s commitment to quality, evident on their website www.parker.com, ensures consistent performance and reliability. This is achieved through rigorous quality control, from material selection to final inspection.
Technical Features of Parker O-Rings
Parker O-rings are available in a vast array of materials, each tailored to specific application requirements. The choice of material depends on factors such as temperature, pressure, and the type of fluid being sealed. Consult the Parker O-Ring Handbook available on www.parker.com for detailed material selection guidance. The following table compares key technical features:
| Feature | Description |
|---|---|
| Material | Wide range including NBR, HNBR, EPDM, FKM, FVMQ, Silicone, and FFKM. |
| Hardness (Shore A) | Typically ranges from 40 to 90 Shore A, affecting compression and resilience. |
| Temperature Range | Varies greatly depending on the chosen material. |
| Pressure Rating | Dependent on material, size, and application (static vs. dynamic). |
| Chemical Resistance | Each material offers varying degrees of resistance to different chemicals. |
| Size | Available in standard metric and imperial sizes, as well as custom dimensions. |
Different Types of Parker O-Rings
The variety of applications necessitates different O-ring types. These differences often relate to the materials used and the intended sealing environment. Parker’s cross-reference tool on crossref.parker.com helps identify suitable replacements. The table below highlights key distinctions:

FAQs
1. What are the most common materials used in Parker O-rings?
Parker O-rings utilize a wide range of materials, including Nitrile Butadiene Rubber (NBR), Hydrogenated Nitrile Butadiene Rubber (HNBR), Ethylene Propylene Diene Monomer (EPDM), Fluoroelastomer (FKM), Fluorosilicone (FVMQ), Silicone (VMQ), and Perfluoroelastomer (FFKM). The selection depends on the application’s specific requirements.
2. How do I choose the right Parker O-ring for my application?
Material selection is critical. Consider factors like temperature range, pressure, chemical compatibility with the operating fluids, and whether the seal will be static or dynamic. Parker’s resources, including online tools and handbooks, provide detailed guidance.
3. Where can I purchase Parker O-rings in China?
Parker O-rings are readily available through authorized distributors across China. These distributors often maintain stock and offer technical support. Consult Parker’s website for a list of authorized distributors in your region.
4. What is the difference between static and dynamic O-ring seals?
Static seals involve stationary parts, whereas dynamic seals involve relative movement between the sealed components. The choice of O-ring material and design differs based on this distinction, with dynamic seals requiring more resilient materials to handle the movement.
5. How long do Parker O-rings typically last?
The lifespan of a Parker O-ring depends on several factors: material, operating conditions (temperature, pressure, chemicals), and application type (static or dynamic). Proper installation and regular maintenance are crucial to maximizing the lifespan. Refer to Parker’s documentation for estimated service life.
