Product Overview
A Micro usb cover cap protects an unused connection with a small flexible closure. The cap must follow the intended connector profile and the space around it, including any asymmetry that determines orientation. Custom size and color options allow the cover to suit the device instead of being forced into a nearly matching opening.
Align the cap before insertion and check that it reaches its intended seat without resistance from an internal feature. Leave a practical portion accessible for removal; a cover pushed beyond that position can be difficult to withdraw without a tool near the port. Keep the protective portion clean while the connection is in use, and inspect it before replacing it. Do not press lint or a loose particle into the opening beneath the rubber. If the cap twists or repeatedly falls away, review its actual fit with the enclosure rather than assuming all Micro USB surroundings are identical. Replace a torn insertion edge before small fragments can separate during handling.
- Material options
- Rubber compound options, customized alongside the profile and contact conditions.
- Hardness selection
- Solid rubber options: 30–90 Shore A. Align the cap before insertion and check that it reaches its intended seat without resistance from an internal feature.
- Custom geometry
- Custom size and color options allow the cover to suit the device instead of being forced into a nearly matching opening.
- Fit evaluation
- If the cap twists or repeatedly falls away, review its actual fit with the enclosure rather than assuming all Micro USB surroundings are identical.
- 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.
