Product Overview
A silicone rubber plug used as a USB dust cover closes an unused opening with a flexible custom part. The outer shape should suit both the port area and the way the device is held. An exposed edge located in the user's grip can be disturbed repeatedly even when the engaging section fits correctly.
Review the product through its usual handling positions. The plug face should not be peeled by the palm or caught by a finger moving across the housing. At the same time, it needs an accessible area for deliberate removal. Custom dimensions allow that balance to be considered around the exact enclosure and connector location.
The selected material and color can follow the device design. Inspect the fit if the cover repeatedly comes out during handling, since the cause may be the exposed shape rather than insufficient insertion depth. Keep the inner surface clean and avoid pushing the plug farther inward to solve an access problem. Its intended seating position should remain defined by the custom interface.
- Material options
- Custom silicone compound; formulation and geometry developed together.
- Hardness selection
- Silicone options: 20–80 Shore A. Inspect the fit if the cover repeatedly comes out during handling, since the cause may be the exposed shape rather than insufficient insertion depth.
- Custom geometry
- Custom dimensions allow that balance to be considered around the exact enclosure and connector location.
- Fit evaluation
- Review the product through its usual handling positions.
- 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.
