Groove Design & Seal Fit
Groove Dimension Matching
The groove width, groove depth, and O-ring cross section need to be matched according to the selected metric FKM O Ring size. Proper dimension control ensures the O-ring is compressed correctly after installation and maintains contact with the sealing surfaces.
Compression Control
The sealing effect depends on the amount of O-ring compression inside the gland. Insufficient compression may reduce sealing contact, while excessive compression can increase friction and accelerate wear during repeated movement or long-term operation.
Gland Design Considerations
When selecting a metric FKM O Ring, the inside diameter, cross section, and gland dimensions should be evaluated together. The correct combination helps prevent issues such as extrusion, deformation, or improper fitting under the specified operating conditions.
FAQ
How do I select the correct metric O ring size?
The correct size is selected based on the inside diameter (ID), cross section (CS), and groove dimensions. The O ring size should match the gland design to achieve the required compression after installation.
What is the difference between Metric O Rings and AS568 O Rings?
Metric O Rings are defined by metric dimensions, while AS568 O Rings follow inch-based aerospace size standards. The two systems use different sizing references and should be selected according to the equipment design requirements.
Can Metric FKM O Rings be used for hydraulic and pneumatic applications?
Yes. Metric FKM O Rings can be used in hydraulic and pneumatic systems where FKM material compatibility is required. The suitability depends on pressure, temperature, movement conditions, and the sealing groove design.
Can you manufacture custom metric FKM O Rings?
Yes. Chaoyue can manufacture custom metric O Rings according to drawings, samples, or groove specifications, including custom dimensions, hardness, color, and packaging requirements.
