Product Overview

Neoprene rubber washers place a compliant annular layer within a hardware or joint assembly. Their inner diameter, outside diameter, and thickness can be customized to the supporting faces. For vibration related use, the amount and direction of loading determine how the installed washer behaves.

The hardware stack should establish the intended compression without cutting into the rubber. A narrow bearing face or a sharp edge can concentrate force locally, while excessive tightening may restrict the movement the rubber was meant to accommodate. Evaluate the washer with the actual fastener, supporting parts, and available clearance rather than judging it as a loose ring.

Choose the neoprene formulation for the surrounding temperature and contact substances. Inspect the assembly for unintended rigid contact that bypasses the rubber interface. After operation or disassembly, look for uneven deformation and changes in the seating position. A washer used as a gasket also needs a separate assessment of its sealing contact; a suitable vibration interface does not automatically establish the performance required at a fluid boundary.

Material options: Neoprene. Custom formulation and color for the intended contact conditions.
Hardness selection: Rubber: 30–90 Shore A. A narrow bearing face or a sharp edge can concentrate force locally, while excessive tightening may restrict the movement the rubber was meant to accommodate.
Custom dimensions: Evaluate the washer with the actual fastener, supporting parts, and available clearance rather than judging it as a loose ring.
Fit & assembly: Neoprene rubber washers place a compliant annular layer within a hardware or joint assembly.
Use & inspection: Inspect the assembly for unintended rigid contact that bypasses the rubber 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.
