Product Overview

Silicone rubber tubing plugs occupy a defined section of the tube opening with a small solid body. The available internal depth should allow the intended contact region to seat without the end of the plug striking a shoulder or restriction first.

ETOL offers custom size, material, hardness and color. Compare the finished tube bore and any change in section near the end. Select the compound for the contents and operating conditions, and leave enough exposed handling space for the required removal method.

Introduce the closure squarely and stop if it meets unexpected resistance. A flexible body can bend inside the tube while the visible head appears nearly seated, so inspect the actual fit instead of pushing deeper. Evaluate the closure function with the complete system under its specified conditions. During service, follow the appropriate release procedure before removal. Check the inserted surface for cuts or scoring and inspect the corresponding tube feature before replacing a damaged plug, rather than repeatedly fitting another part against the same sharp internal edge.

Material options: Custom silicone compound; formulation and geometry developed together.
Hardness selection: Silicone options: 20–80 Shore A. A flexible body can bend inside the tube while the visible head appears nearly seated, so inspect the actual fit instead of pushing deeper.
Custom geometry: The available internal depth should allow the intended contact region to seat without the end of the plug striking a shoulder or restriction first.
Fit evaluation: Evaluate the closure function with the complete system under its specified conditions.
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.
