Product Overview
A custom USB rubber cover is shaped around the port and the space available on its enclosure. This matters when a connector sits in a recess or close to another opening: the cover needs enough engagement to stay in position without obstructing adjacent controls or connections. ETOL can adjust its structure, size, material, hardness and color for the equipment design.
The intended purpose is to shield an idle USB port from dust and moisture exposure. Protection depends on the complete fit between the flexible part and its mating surfaces. The product information does not assign an enclosure ingress rating, so the cover should be assessed as part of the finished housing for any application requiring a defined water barrier.
During a trial assembly, close the cover with the same hand motion a user will employ. Check whether its edge lies flat or rolls inward near a corner. Repeatedly opening it should not require a sharp tool. Wipe away surface contamination before closing, and replace a cover that has stretched enough to become loose.
- Material options
- Custom silicone compound; formulation and geometry developed together.
- Hardness selection
- Silicone options: 20–80 Shore A. Protection depends on the complete fit between the flexible part and its mating surfaces.
- Custom geometry
- Repeatedly opening it should not require a sharp tool.
- Fit evaluation
- Check whether its edge lies flat or rolls inward near a corner.
- 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.
