Product Features
Manufactured to AS568 Standard
Each O-ring is produced in accordance with the AS568 inch-size standard, ensuring consistent inside diameter, cross-section, and dimensional tolerances. Standardized sizing allows easy interchangeability and reliable installation across a wide range of industrial sealing systems.
Reliable Sealing Performance
Designed to prevent the leakage of liquids and gases, these O-rings provide stable sealing performance under pressure while maintaining good elasticity and wear resistance. They are suitable for dynamic and static sealing applications in various operating conditions.
Available in Multiple Materials
AS568 O-rings can be manufactured in FKM, NBR, HNBR, EPDM, Silicone, Fluorosilicone, Polyurethane, and other elastomers to meet different temperature ranges, chemical compatibility, and application requirements. Standard black and custom colors are available upon request.
Wide Industrial Applications
These O-rings are widely used in hydraulic systems, pneumatic equipment, pumps, valves, automotive components, food processing equipment, and general industrial machinery where standardized inch-size sealing solutions are required.

FAQ
What does AS568 mean?
AS568 is the standard inch-size specification for O-rings. It defines the inside diameter, cross-section, and dash number, ensuring dimensional consistency and interchangeability.
Which material should I choose?
The right material depends on the working environment. FKM offers excellent chemical and heat resistance, NBR performs well in oil applications, while EPDM is commonly used for water, steam, and outdoor environments.
Can you produce custom sizes?
Yes. In addition to standard dimensions, custom sizes can be manufactured according to drawings, samples, or specific application requirements.
How do I select the correct size?
Selection is based on the required inside diameter, cross-section, operating pressure, and groove dimensions. Our technical team can also assist with size selection.
