Product Overview
A small custom plug with hole surrounds a passing feature while its outside fits a separate opening. For a silicone version, the rubber geometry must coordinate these inner and outer contact areas. The hole cannot be ignored when evaluating the closure, particularly if the assembly is expected to resist water exposure.
Define what passes through the center and how it is positioned. The bore may change shape as the outer body is compressed during fitting, so evaluate the passing component after the plug is seated. Avoid using an excessively tight outer fit that squeezes the center out of its intended alignment. The surrounding head or stop also needs enough space to reach its proper position.
Select the material for the actual exposure and inspect both interfaces in the finished assembly. An open center left unoccupied changes the closure condition, even if the outer profile fits neatly. Keep the bore free from particles and prevent sharp ends from cutting the rubber during insertion. Any required water resistance should be established for this complete fitted arrangement and its intended conditions.
- Material options
- Custom silicone compound; formulation and geometry developed together.
- Hardness selection
- Silicone options: 20–80 Shore A. Any required water resistance should be established for this complete fitted arrangement and its intended conditions.
- Custom geometry
- The bore may change shape as the outer body is compressed during fitting, so evaluate the passing component after the plug is seated.
- Fit evaluation
- Select the material for the actual exposure and inspect both interfaces in the finished assembly.
- Color & OEM
- Custom colors; OEM identification positioned outside closure contact surfaces.

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.
