Product Overview

A dustproof hole plug should match the finished opening and its retained profile, not merely a size printed beside a similar-looking part. This selection includes 8 mm, 10 mm and 12 mm references, with custom dimensions available for other arrangements.

Identify which measurement applies to the hole and which belongs to the head or inserted body. The panel thickness and any groove determine where the plug is retained. Two parts with similar visible heads may therefore suit different openings.

ETOL offers material, hardness and color customization. Compare the selected profile with the actual panel, including finish buildup and nearby features that could prevent the flange from sitting flat. Where dust or moisture exclusion is needed, evaluate the full perimeter contact in the intended assembly.

Keep different sizes distinguishable during installation and inspect each seat before access is concealed. A part that feels unusually easy or difficult to insert calls for a dimensional check rather than more force. During replacement, remove all remnants from the opening and compare the new plug's retained section with the intended seat. Do not use the distorted outline of an old component as the only measurement, since wear or compression may have changed its original shape.

Material options: Rubber compound options, customized alongside the profile and contact conditions.
Hardness selection: Solid rubber options: 30–90 Shore A. A part that feels unusually easy or difficult to insert calls for a dimensional check rather than more force.
Custom geometry: A dustproof hole plug should match the finished opening and its retained profile, not merely a size printed beside a similar-looking part.
Fit evaluation: Keep different sizes distinguishable during installation and inspect each seat before access is concealed.
Color & OEM: Custom colors; OEM identification positioned outside closure contact surfaces.

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.
