Product Overview
A silicone rubber washer provides a flat sealing section for a water exposed joint with suitable mating faces. Its contact differs from that of an O-ring seated in a groove, so the selected format should follow the hardware. Define the supported face area and closing gap before choosing a thickness that appears convenient during assembly.
Check the inner opening and outer edge against the completed connection. Keep the rubber from extending into a passage or an unsupported recess. The formulation should suit the actual water conditions, temperature, and cleaning substances rather than being selected from the material name alone.
Place the washer flat and centered before closure. Bring the faces together evenly and inspect for an edge dragged by rotating hardware. Assess the complete joint under the intended exposure. During maintenance, examine the contact band for localized flattening or extrusion and compare it with the mating surfaces. Correct an uneven support before replacing the washer so the next part receives the intended compression around the whole opening.
- Material options
- Custom silicone compound; formulation and geometry developed together.
- Hardness selection
- Silicone options: 20–80 Shore A. Its contact differs from that of an O-ring seated in a groove, so the selected format should follow the hardware.
- Custom geometry
- Keep the rubber from extending into a passage or an unsupported recess.
- Fit evaluation
- Define the supported face area and closing gap before choosing a thickness that appears convenient during assembly.
- Color & OEM
- Custom colors; OEM markings clear of the working interface.

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.
