Product Overview

A round flat silicone rubber washer can be customized in color while keeping its main function at the mating faces. Color may help distinguish versions during assembly, but the inside diameter, outside diameter, and thickness still determine the fit. Keep any color convention associated with those actual dimensions and the selected compound.

Check the support beneath the full washer face. A portion left hanging into a recess can deform differently from the supported region when the joint closes. The center opening should remain clear of the intended passage or fastener without allowing the washer to shift excessively.

Place the washer flat and centered before bringing the adjoining faces together. Avoid dragging it around with rotating hardware, which can distort the contact band. Select silicone for the actual medium and temperature at the joint, and assess any sealing duty on the assembled connection. During service, inspect for uneven flattening or an inner edge pushed into the opening before fitting the correct replacement version.

Material options: Silicone. Custom formulation and color for the intended contact conditions.
Hardness selection: Silicone: 20–80 Shore A. A portion left hanging into a recess can deform differently from the supported region when the joint closes.
Custom dimensions: Color may help distinguish versions during assembly, but the inside diameter, outside diameter, and thickness still determine the fit.
Fit & assembly: The center opening should remain clear of the intended passage or fastener without allowing the washer to shift excessively.
Use & inspection: During service, inspect for uneven flattening or an inner edge pushed into the opening before fitting the correct replacement version.

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.
