Product Overview

A threaded silicone rubber stopper should engage its mating opening in alignment and reach the intended closure seat without excessive twisting. The thread profile and the surface that establishes final contact should be matched as part of the same design.

ETOL can customize dimensions, compound, hardness and color. Compare the mating thread, available engagement depth and clearance around the handling portion. A stopper that starts into a similarly sized opening is not necessarily correctly matched across its full thread length.

Clean the interface and begin engagement squarely. Stop if the part tilts or requires unexpected force, then inspect for debris or a mismatch before proceeding. Use the assembled condition specified for the closure and evaluate its required function under the intended exposure. During removal, follow the designed release direction and keep sharp tools from tearing molded thread features. Inspect the engaged region before reuse. If the thread has distorted, correct the mating or handling issue before replacement rather than tightening another soft part through the same resistance.

Material options: Custom silicone compound; formulation and geometry developed together.
Hardness selection: Silicone options: 20–80 Shore A. Compare the mating thread, available engagement depth and clearance around the handling portion.
Custom geometry: A stopper that starts into a similarly sized opening is not necessarily correctly matched across its full thread length.
Fit evaluation: Use the assembled condition specified for the closure and evaluate its required function under the intended exposure.
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.
