Frequently Asked Questions (FAQs)
What materials are commonly used for O-rings in Chinese factories?
Chinese factories often use a variety of materials for O-rings, including NBR (Nitrile), FKM (Fluororubber), EPDM (Ethylene Propylene Diene Monomer), Silicone, HNBR (Hydrogenated Nitrile Butadiene Rubber), and FFKM (Perfluoroether Rubber). Each material has its own set of properties, such as temperature resistance, chemical resistance, and durability, making them suitable for different applications.
How do I determine the size of an O-ring I need?
To determine the size of an O-ring, you need to know the inner diameter (ID) and the cross-section (CS) of the O-ring. The outer diameter (OD) can be calculated using the formula: OD = ID + 2 x CS. You can refer to standard O-ring size charts like AS568, ISO 3601, or DIN 3771, or contact the manufacturer for custom sizes if needed.
What are the typical applications of O-rings produced in Chinese factories?
O-rings from Chinese factories are used in a wide range of industries, including automotive, aerospace, hydraulics and pneumatics, oil and gas, semiconductor processing, food processing, and medical equipment. They are essential for sealing and preventing leakage in various mechanical and hydraulic systems.
Can I customize the size and shape of O-rings from Chinese manufacturers?
Yes, you can customize the size and shape of O-rings from Chinese manufacturers. If the cross-section or outline shape is not standard, you can provide a drawing or specifications, and the manufacturer will create a custom mold for production. This allows for flexibility in meeting specific application requirements.
What is the typical hardness range and working temperature for O-rings from Chinese factories?
The hardness of O-rings from Chinese factories usually ranges from 30 to 90 Shore A, depending on the material and application. The working temperature can vary widely, from -60°C to 350°C, depending on the material used. For example, NBR O-rings typically work between -40°C and 120°C, while FFKM O-rings can handle temperatures up to 326°C.
