Frequently Asked Questions (FAQs)

Frequently Asked Questions About Common O-Ring Sizes in Chinese Factories

What are the standard sizes for O-rings available in Chinese factories?

Chinese factories offer a wide range of standard O-ring sizes, including those that conform to international standards such as AS568 (USA), BS1516 (UK), DIN 3771 (Germany), JIS B 2401 (Japan), ISO 3601 (International), and GB 3452.1 (China). These sizes are specified by their inside diameter (ID), outside diameter (OD), and cross-section (CS) or width.

Can I get custom-sized O-rings from Chinese manufacturers?

Yes, you can get custom-sized O-rings from Chinese manufacturers. Many factories, such as those mentioned, offer customization services where they can produce O-rings based on your specific requirements. This includes non-standard sizes, unique materials, and special colors. You can provide your specifications or samples, and they will manufacture the O-rings accordingly.

What materials are commonly used for O-rings in Chinese factories?

The most commonly used materials for O-rings in Chinese factories include NBR (Nitrile), FKM (Viton), Silicone, EPDM, HNBR, and FFKM. Each material has its own properties and is suited for different applications. For example, NBR is good for general use, FKM is excellent for high-temperature and chemical resistance, and Silicone is often used in medical and food industries.

How do I specify the size of an O-ring when ordering from a Chinese factory?

To specify the size of an O-ring, you typically need to provide the inside diameter (ID) and the cross-section (CS) or width. The outside diameter (OD) can be calculated using the formula: OD = ID + CS * 2. For example, an O-ring with an ID of 20 mm and a CS of 2 mm would have an OD of 24 mm.

What is the typical hardness range for O-rings produced in Chinese factories?

The hardness of O-rings is usually measured in Shore A units and ranges from 40 to 90. However, the most commonly used hardness is around 70 Shore A, which balances ease of installation and durability. For specific applications, such as high-pressure sealing, harder O-rings (85-90 Shore A) may be required, while softer O-rings (60-70 Shore A) are better for easier installation but may be more prone to damage.
