Frequently Asked Questions (FAQs)

Frequently Asked Questions About O-Ring Dimension Chart Factories in China

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

Chinese factories typically follow international standards such as AS568, BS1516, JIS B 2401, DIN 3771, and ISO 3601 for o-ring sizes. These standards specify various cross-sections and inner and outer diameters. For example, the AS568 standard includes cross-sections like 1.78 mm, 2.62 mm, and 3.53 mm, among others. This ensures compatibility and consistency across different applications.

Can I customize o-ring sizes and materials according to my needs?

Yes, you can customize o-ring sizes and materials to fit your specific requirements. Many Chinese manufacturers, such as Savvy and Yiho, offer customization options where you can specify the inner diameter, cross-section, and material type (e.g., NBR, FKM, EPDM). They can produce custom o-rings in various shapes and sizes based on your drawings or specifications.

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

Chinese factories use a variety of materials for o-rings, including NBR (nitrile), FKM (fluorocarbon), EPDM (ethylene propylene diene monomer), silicone, HNBR (hydrogenated nitrile), and FFKM (perfluoroether). Each material has different properties, such as temperature resistance, chemical resistance, and durability, making them suitable for various applications like automotive, aerospace, and industrial equipment.

How do I ensure the quality and reliability of o-rings from Chinese factories?

To ensure quality and reliability, look for factories that are certified with international standards like ISO 9001. These certifications indicate that the factory follows strict quality control processes. Additionally, many factories offer unconditional replacement for non-qualifying products and provide free samples for testing. Checking for third-party audits and customer reviews can also help you make an informed decision.

What is the typical production capacity and lead time for o-ring orders in Chinese factories?

Chinese factories often have high production capacities, producing tens of millions of o-rings per month. The lead time can vary depending on the order size and complexity, but standard orders typically take a few weeks. For custom orders, the lead time might be slightly longer due to the need for mold creation and testing. However, many factories aim to deliver products quickly while maintaining high quality standards.
