Frequently Asked Questions (FAQs)

Frequently Asked Questions About Standard O-Ring Dimensions in Chinese Factories

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

You can find O-rings made from a variety of materials, including Nitrile (NBR), Fluoroelastomer (FKM), Ethylene Propylene Diene Monomer (EPDM), Hydrogenated Nitrile (HNBR), Silicone (VMQ), and Perfluoroelastomer (FFKM). Each material has its own unique properties, such as temperature resistance, chemical resistance, and wear resistance, making them suitable for different applications.

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

Standard O-ring sizes are often based on international standards like AS568 (USA), ISO 3601 (Universal), and others. These standards specify various cross-sections and inner diameters. For example, common cross-sections include 1.78 mm, 2.62 mm, 3.53 mm, and more. You can find detailed size charts from manufacturers to select the right size for your needs.

How do I choose the right O-ring size for my application

To choose the right O-ring size, you need to know the inner diameter (ID) and the cross-section (CS) of the O-ring. You can refer to the standard size charts provided by manufacturers or consult with them directly. It’s also important to consider the material and performance requirements of your application, such as temperature, pressure, and chemical resistance.

What is the minimum order quantity (MOQ) for standard O-rings from Chinese factories

The minimum order quantity (MOQ) for standard O-rings can vary depending on the manufacturer. Typically, MOQs range from 100 to 1000 pieces. Some factories may offer lower MOQs for certain materials or sizes, while others might require larger orders. Always check with the supplier for their specific MOQ requirements.

How long does it take to receive standard O-rings from Chinese factories

The delivery time for standard O-rings from Chinese factories can vary based on the availability of the size and material you need. For standard sizes, delivery times are generally faster since these are often in stock. However, for non-standard sizes, production may take longer as it involves making a custom mold.
