Product Overview
A custom silicone micro USB cover protects an unused connector opening through a matched flexible cap profile. Its outer head should leave access to neighboring ports and controls, while the inserted section must suit the actual micro USB port and surrounding enclosure recess.
ETOL offers custom dimensions, material, hardness and color. Compare the connector and housing together rather than choosing a cap solely by the visible recess. Keep the electrical contact area clear of excessive insertion pressure and any trapped particles carried by the cover.
Fit the cap through its intended handling feature and stop if it meets unexpected resistance. Check that its head seats without pushing against an adjacent plug or button. Evaluate the desired dust-exclusion function in the completed device arrangement. During cable use, keep the removed cap clean and inspect it before refitting. Replace a torn or distorted piece rather than forcing it into the connector, and avoid using the cover to push debris farther into a port that needs proper cleaning.
- Material options
- Custom silicone compound; formulation and geometry developed together.
- Hardness selection
- Silicone options: 20–80 Shore A. Fit the cap through its intended handling feature and stop if it meets unexpected resistance.
- Custom geometry
- Compare the connector and housing together rather than choosing a cap solely by the visible recess.
- Fit evaluation
- Evaluate the desired dust-exclusion function in the completed device arrangement.
- 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.
