Product Overview
A custom micro usb rubber cap needs to fit both the connector region and the device surface around it. For a water-exclusion design, the contact at that surrounding surface is as relevant as the part that enters the port.
Define the cap profile from the actual enclosure opening, including any recess, edge or nearby feature that affects seating. ETOL supports custom dimensions and elastomer constructions for the intended arrangement. Leave enough handling access for removal without stretching a thin cap edge.
Keep the contact surfaces clean before fitting and inspect the seated perimeter for a local gap or fold. The cap should enter without force against the connector's internal features. Evaluate the completed device for the required exposure conditions rather than treating the loose cap as a standalone seal. After cable use, clean and inspect the cap before it is returned to the port. If the housing or connector changes, recheck the interface so the original cover is not retained merely because its external appearance still seems close.
- Material options
- Rubber compound options, customized alongside the profile and contact conditions.
- Hardness selection
- Solid rubber options: 30–90 Shore A. Leave enough handling access for removal without stretching a thin cap edge.
- Custom geometry
- Define the cap profile from the actual enclosure opening, including any recess, edge or nearby feature that affects seating.
- Fit evaluation
- Evaluate the completed device for the required exposure conditions rather than treating the loose cap as a standalone seal.
- 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.
