Product Overview
A round rubber washer places a flat, compliant ring between circular mating surfaces. It can be customized for uses such as a bottle mouth or pipeline joint, with the material and dimensions chosen for the actual interface. The inside opening, outside edge and thickness determine how much rubber is available on the sealing face.
Match the annular width to the supported area. A broad washer on a narrow rim can leave material unsupported on either side, while an undersized washer may not cover the intended contact band. Check any chamfer or radius near the hole because it can reduce the usable flat face even when the nominal diameters appear correct.
Bring the mating parts together without displacing the ring sideways. If assembly involves rotation, observe whether the washer remains flat or begins to drag with one surface. Select the compound around the fluid and cleaning process, and keep the faces free of residue. A damaged rim or distorted mating part should be corrected as part of service; adding a thicker washer can change closure without resolving the underlying contact problem.
- Material options
- Rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. Evaluate compression across the usable flat face after allowing for the inner chamfer; nominal diameters alone overstate that supported area.
- Custom dimensions
- The inside opening, outside edge and thickness determine how much rubber is available on the sealing face.
- Fit & assembly
- If assembly involves rotation, observe whether the washer remains flat or begins to drag with one surface.
- Use & inspection
- A damaged rim or distorted mating part should be corrected as part of service; adding a thicker washer can change closure without resolving the underlying contact problem.

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.
