Frequently Asked Questions (FAQs)

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

Chinese factories offer a wide range of standard metric sizes for o-rings, adhering to various international standards such as AS568, BS1516, DIN 3771, JIS B 2401, ISO 3601, and GB 3452.1. These sizes include inside diameters (ID) ranging from 0.5mm to 2000mm and cross-sections (thickness) from 0.5mm to 30mm or more, depending on the manufacturer.

How do I specify the size of an o-ring for my needs?

To specify the size of an o-ring, you typically need to provide the inside diameter (ID) and the cross-section (thickness). For example, a standard o-ring size might be given as ID 20 x CS 2 mm. The outside diameter (OD) can be calculated using the formula: OD = ID + CS * 2. This ensures you get the exact size you need for your application.

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

Chinese factories produce o-rings from a variety of materials, including NBR (Nitrile), FKM (Viton), EPDM, Silicone, FFKM, HNBR (Hydrogenated Nitrile Butadiene Rubber), and others. Each material has its own properties and is suited for different applications, such as chemical resistance, temperature range, and durability.

Can I get custom sizes and shapes for my o-ring needs?

Yes, you can get custom sizes and shapes for your o-ring needs. Many Chinese manufacturers have thousands of molds and can produce o-rings according to your specific drawings or samples. They also offer services like mold modification and sample testing to ensure the o-rings meet your requirements.

What is the typical hardness range for o-rings, and how is it measured?

The hardness of o-rings is typically measured in Shore A units, ranging from 40 to 90. For most applications, a hardness of 70 Shore A is commonly used, although silicone rubber often uses 60 Shore A. The hardness affects the ease of installation and the sealing performance, with lower hardness being easier to install but more prone to damage, and higher hardness being more durable but harder to install.
