Product Overview
A flat round rubber sealing component should be matched by its section as well as its circular outline. A flat gasket and a conventional O-ring occupy a seat differently, even when their overall diameters look similar. Custom dimensions and material options allow the selected shape to follow the intended joint.
Examine the mating geometry before selecting a replacement. A flat seat may support a washer-like section across its width, while a groove designed for a circular section controls the rubber differently. Preserve the required profile rather than choosing a ring only because it fits around the center feature.
The material needs to suit the substances and temperature at the interface. Position the seal cleanly and check that it remains flat or properly seated according to its design. Close the assembly through the intended locating arrangement to avoid pinching one side. During servicing, compare the removed part with the required dimensions, recognizing that sustained compression may have changed its shape. Use the specified section for replacement instead of copying a distorted old profile.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. Choose the grade for the actual flat seat or circular-section groove; each arrangement supports silicone deformation differently.
- Custom dimensions
- A flat round rubber sealing component should be matched by its section as well as its circular outline.
- Fit & assembly
- Position the seal cleanly and check that it remains flat or properly seated according to its design.
- Use & inspection
- During servicing, compare the removed part with the required dimensions, recognizing that sustained compression may have changed its shape.

Ordering this custom component
Can the shape be adjusted to my mating parts?
Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.
Which details should be agreed before tooling?
Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.
Can a sample help define the replacement?
A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.
How is the quotation for this part determined?
The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
