Product Overview

A silicone rubber stopper with pull-ring provides a dedicated handling feature for removing the solid closure from its designated opening. The ring should remain accessible once surrounding parts are installed, and the retained body should be sized so removal does not require excessive force through that feature.

Develop the plug profile, ring dimensions and material together. Check how the removal direction lines up with the opening; pulling sideways around an obstruction can load one area of the ring or retained edge differently from the intended method. Custom size and color can follow the assembly design.

Fit the stopper to its designated seat without trapping the pull-ring beneath another component. Any sealing requirement should be evaluated with the complete closure and operating conditions. During maintenance, inspect the ring's connection to the body as well as the contacting surface of the plug. Replace a torn or weakened handling feature rather than continuing to pull it harder, and investigate a changed fit if removal has become unexpectedly difficult.

Material options: Custom silicone compound; formulation and geometry developed together.
Hardness selection: Silicone options: 20–80 Shore A. The ring should remain accessible once surrounding parts are installed, and the retained body should be sized so removal does not require excessive force through that feature.
Custom geometry: Develop the plug profile, ring dimensions and material together.
Fit evaluation: Check how the removal direction lines up with the opening; pulling sideways around an obstruction can load one area of the ring or retained edge differently from the intended method.
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.
