Product Overview

A mini micro USB rubber plug must be selected for the actual connector format used by the device. Mini USB and micro USB openings are different, so the custom molded profile should match the specific interface rather than a general small-port description. The housing recess adds another set of dimensions to check.

Compare the opening shape and the space available around it. The exposed cap needs a practical gripping area without blocking nearby features. Its insertion section should follow the intended path without pressure against an incompatible connector edge.

Clean the cover and surrounding housing before fitting. Use the correct orientation and controlled movement, stopping if the part does not seat normally. During care, inspect small retained and handling features for damage after removal. Keep different cap variants separated if they look similar at a glance. A replacement should match the required connector and enclosure geometry rather than being selected solely because its overall size appears suitable for the opening.

Material options

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.
