Quality Control
Raw Material Inspection
All elastomer materials are inspected before production to verify material consistency and compliance with specified performance requirements. This helps ensure stable processing and reliable sealing performance in different applications.
Precision Dimensional Control
Each production batch is manufactured with controlled processes to maintain accurate inside diameter, cross-section, and dimensional tolerances. Regular dimensional inspections help ensure consistency across standard metric sizes.
Final Quality Verification
Before shipment, finished products undergo final inspections, including appearance checks, dimensional verification, and hardness testing. Each batch is reviewed to help ensure it meets customer specifications and quality requirements.
FAQ
What are Metric Size O Rings?
O Rings are sealing rings manufactured in metric dimensions. They are commonly used to prevent the leakage of liquids and gases in a wide range of industrial sealing applications.
How do I choose the correct size?
The correct size is determined by the inside diameter (ID), cross-section (CS), and groove dimensions. If you are unsure, our technical team can assist with product selection.
Can you manufacture custom sizes?
Yes. Custom dimensions, materials, hardness, colors, and packaging can be produced according to your drawings, samples, or application requirements.
What industries are these products used in?
They are widely used in hydraulic systems, pneumatic equipment, pumps, valves, automotive components, food processing equipment, and general industrial machinery.
