Product Overview
A mini USB anti dust plug should fit the intended connector opening while leaving neighboring sockets and controls accessible. Its exposed head can occupy more space than the inserted section, making the complete housing layout part of selection. Check that the cover can be removed without first disturbing another connected cable.
Match the insertion profile and depth to the actual port. The cap should not be forced against internal connector features or used to correct a damaged opening. Choose the rubber configuration around the device environment and the expected removal frequency.
Keep the plug clean while it is out of the port, and remove loose debris before reinserting it. Fit gently in the correct orientation rather than turning it until it seems to grip. Inspect the handling area for tears during repeated use. Where a defined dust or water protection level is required, assess the completed device with its actual cover contact; the removable plug's general form does not establish that performance on its own.
- Material options
- Rubber compound options, customized alongside the profile and contact conditions.
- Hardness selection
- Solid rubber options: 30–90 Shore A. Match the insertion profile and depth to the actual port.
- Custom geometry
- A mini USB anti dust plug should fit the intended connector opening while leaving neighboring sockets and controls accessible.
- Fit evaluation
- Check that the cover can be removed without first disturbing another connected cable.
- 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.
