Product Overview
Flat thin rubber washers provide a low profile layer where the assembly has limited space for rubber thickness. Their flexibility makes placement important: a thin edge can fold or shift during closure without producing an obvious increase in overall height. Select the inner and outer dimensions so the washer is fully supported where it needs to make contact.
Consider the joint temperature and the selected compound together. If the mating parts change their gap as they heat, assess the available compression across that cycle. A thin washer should not be expected to compensate for substantial surface damage or a closing face that remains uneven.
Place the part flat and centered before fastening. Keep rotating hardware from dragging the rubber into a crease, and inspect the perimeter where accessible after assembly. During removal, look for cuts around the center hole and a permanently wrinkled region. Preserve the intended thickness during replacement; stacking multiple thin washers can introduce additional movement and change the contact arrangement between the adjoining components.
- Material options
- Rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. A thin washer should not be expected to compensate for substantial surface damage or a closing face that remains uneven.
- Custom dimensions
- Flat thin rubber washers provide a low profile layer where the assembly has limited space for rubber thickness.
- Fit & assembly
- Place the part flat and centered before fastening.
- Use & inspection
- Preserve the intended thickness during replacement; stacking multiple thin washers can introduce additional movement and change the contact arrangement between the adjoining components.

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.
