Frequently Asked Questions (FAQs)
Frequently Asked Questions About O-Ring Sizes in Metric Factories in China
How do I specify the size of an O-ring?
When specifying the size of an O-ring, you typically need to provide the inside diameter (ID), outside diameter (OD), and the cross-section (CS) or width. A standard way to specify this is by giving the ID and CS, for example, “ID 20 x CS 2 mm.” The outside diameter can be calculated using the formula: OD = ID + CS * 2.
What are the common materials used for O-rings in Chinese factories?
Chinese factories often use a variety of materials for O-rings, including Nitrile (NBR), Ethylene Propylene Diene Monomer (EPDM), Fluorocarbon (FKM), Silicone (SIL), and Hydrogenated Nitrile Butadiene Rubber (HNBR). Each material has its own characteristics and is suited for different applications and environments.
What are the standard sizes and certifications for O-rings in China?
O-rings in China are manufactured according to various international and local standards such as AS568 for the USA, BS1516 for the UK, DIN 3771 for Germany, JIS B 2401 for Japan, ISO 3601 for international use, and GB 3452.1 for China. These standards ensure consistency and quality. Additionally, many Chinese manufacturers hold certifications like UL, FDA, ROHS, and REACH.
How do I choose the right hardness for my O-ring?
The hardness of an O-ring is measured in Shore A units and typically ranges from 40 to 90. For most applications, a hardness of 60-70 is suitable, but it depends on the specific use. Softer O-rings are easier to install but may be prone to damage, while harder O-rings are more durable but harder to install. For high-pressure applications, a hardness of 85-90 is often recommended.
Can I customize the size and color of my O-rings?
Yes, you can customize both the size and color of your O-rings. Many Chinese manufacturers offer OEM and ODM services, allowing you to specify custom sizes and materials based on your design drawings or samples. For colors, you can provide the standard RAL or Pantone color number, although choosing less common colors may increase the cost and minimum order quantity.
