Product Overview

A small silicone rubber plug with hole provides two related interfaces: its outer body fits the opening, and its internal passage accommodates the specified through-component. The thickness of rubber remaining around the hole should suit the intended geometry without local overstretching.

ETOL can customize dimensions, materials, hardness and colors. Define the passage location and the finished size of the tube or wire before selecting the outer profile. An apparently centered hole can become offset in use if the through-component is pulled sideways by its support.

Fit the parts without dragging sharp ends against the bore. Seat the outer plug and then secure the routed component in its intended position, checking that the rubber has not distorted. Evaluate any required sealing function with both interfaces assembled. During removal, support the through-component separately rather than using it to lever the plug from the opening. Inspect the hole edge and outer seat for damage before reuse, and reassess the profile if a replacement tube or cable changes the contact dimensions.

Material options: Custom silicone compound; formulation and geometry developed together.
Hardness selection: Silicone options: 20–80 Shore A. During removal, support the through-component separately rather than using it to lever the plug from the opening.
Custom geometry: A small silicone rubber plug with hole provides two related interfaces: its outer body fits the opening, and its internal passage accommodates the specified through-component.
Fit evaluation: Evaluate any required sealing function with both interfaces assembled.
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.
