Product Overview

The waterproof silicone cover is presented as an anti-dust USB plug for a matching opening. Its practical role is to close the port when a cable is absent. The silicone part can be customized in shape, hardness, dimensions and color, allowing the closure to be developed around the actual equipment interface.

A useful fit starts with the contact perimeter. The plug must reach its intended seating position without being stopped by a neighboring ledge, and its sealing area must remain free of grit. The product name alone does not establish a water depth, exposure duration or ingress protection classification for the finished device.

Before closing a recently exposed port, make sure moisture is not being enclosed behind the plug. Clean the accessible exterior gently and allow it to dry; avoid pushing cleaning tools into the connector contacts.

If users remove the plug often, include that handling pattern in the fit evaluation. Check that the edge remains easy to grasp after repeated closure and that removal does not distort the surrounding port opening. Replace damaged plugs instead of relying on extra insertion force to restore contact.

Material options
Custom silicone compound; formulation and geometry developed together.
Hardness selection
Silicone options: 20–80 Shore A. If users remove the plug often, include that handling pattern in the fit evaluation.
Custom geometry
The silicone part can be customized in shape, hardness, dimensions and color, allowing the closure to be developed around the actual equipment interface.
Fit evaluation
Check that the edge remains easy to grasp after repeated closure and that removal does not distort the surrounding port opening.
Color & OEM
Custom colors; identification clear of connectors and removal features.

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.
