Frequently Asked Questions (FAQs)
What are the key dimensions to consider when selecting an o-ring from a Chinese manufacturer?
When selecting an o-ring, you need to consider three main dimensions: the inner diameter (ID), the outer diameter (OD), and the cross-section (CS) or width. The OD can be calculated using the formula: OD = ID + 2 * CS. These dimensions are crucial for ensuring the o-ring fits properly and functions as intended in your application.
What are the standard o-ring size charts used by Chinese manufacturers?
Chinese manufacturers often refer to several standard o-ring size charts, including AS568 (USA), BS1516 (UK), DIN 3771 (Germany), JIS B 2401 (Japan), ISO 3601 (International), and GB 3452.1 (China). These standards help ensure consistency and compatibility across different regions and applications.
What materials are commonly used for o-rings produced in China?
Chinese manufacturers produce o-rings from a variety of materials, including NBR (Nitrile), FKM (Viton), EPDM, HNBR, Silicone, and FFKM (Kalrez). Each material has its own set of properties and is suited for different applications, such as resistance to chemicals, temperature, and abrasion.
How do I choose the right hardness for my o-ring?
The hardness of an o-ring, measured in Shore A units, is important for its performance. Generally, o-rings range from Shore A 40 to 90. For most applications, a hardness of 60-70 is suitable, but for higher sealing pressures, you may need o-rings with a hardness of 85-90. Lower hardness makes installation easier but may lead to issues like peeling or extrusion.
Can I customize the color and size of o-rings from Chinese manufacturers?
Yes, you can customize both the color and size of o-rings. Manufacturers can produce o-rings in various colors based on your requirements, though common colors like black, green, and red are more cost-effective. Additionally, many manufacturers offer custom sizes beyond the standard charts, allowing you to specify the exact dimensions you need for your application.
