Product Overview
A micro usb protective cover cap should remain clean while it is removed for cable connection. Dust collected on its inserted section can be carried into the port when the cover is fitted again, undermining its protective purpose.
ETOL can customize the dimensions, material, hardness and color around the device interface. Match the inserted portion and outer head to the actual connector and enclosure opening. Leave enough accessible area to release the cap without prying at the connector with a sharp tool.
During use checks, assess removal, temporary placement and refitting as a complete sequence. Keep the cap away from loose debris and inspect its edge before returning it to the port. Seat it gently and stop if it has distorted or no longer enters naturally. Evaluate the required dust protection on the finished device with the selected cap. Replace a split contact region rather than using repeated pressure to make it sit flat, and reassess the profile if a protective case changes access around the opening.
- Material options
- Rubber compound options, customized alongside the profile and contact conditions.
- Hardness selection
- Solid rubber options: 30–90 Shore A. During use checks, assess removal, temporary placement and refitting as a complete sequence.
- Custom geometry
- Match the inserted portion and outer head to the actual connector and enclosure opening.
- Fit evaluation
- Evaluate the required dust protection on the finished device with the selected cap.
- 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.
