Product Overview
An Anti dust cover protects an unused USB area with a custom silicone cap. Its shape should account for the whole local layout, including buttons, indicator windows or other openings beside the connection. The protective cover should not become an obstruction when the rest of the device is being used.
Check the cap with the device fully assembled. A wide removal edge may be convenient in isolation but cover a neighboring feature once fitted. Choose the outer profile and gripping area around that space, while keeping the inserted or retained region matched to the USB opening. Structure, dimensions, material, hardness and color can be customized. Before each replacement, remove debris from the cap itself so its protective surface does not carry dirt into the port. Withdraw it by the intended grip rather than pulling across an adjacent control. If the cover deforms enough to interfere with another function, review its fit and replace the part instead of trimming its edge during routine use.
- Material options
- Custom silicone compound; formulation and geometry developed together.
- Hardness selection
- Silicone options: 20–80 Shore A. A wide removal edge may be convenient in isolation but cover a neighboring feature once fitted.
- Custom geometry
- Choose the outer profile and gripping area around that space, while keeping the inserted or retained region matched to the USB opening.
- Fit evaluation
- Check the cap with the device fully assembled.
- 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.
