Product Overview

A Silicone Washer For Glass Bottle closure should sit within its intended contact area without being pinched against an exposed rim edge. The washer geometry needs to correspond with the bottle and closing component as a complete interface.

Select the compound for the contents and cleaning process. Cut or molded forms can suit different profiles, but the inner diameter, outer footprint and thickness must match the space provided by the actual closure. A similar-looking washer from another bottle may reach a different assembled contact.

Inspect the glass rim and closure seat before fitting, keeping both free of damage and residue. Place the washer without twisting it and verify that it stays centered as the closure is applied by its intended method. Evaluate the required sealing function on the completed bottle arrangement. During removal, keep sharp points away from the rubber and glass. Replace a cut or deformed washer after checking the mating surfaces, and avoid stacking another washer over it to hide an uneven seat or altered fit.

Material options: Silicone. Custom formulation and color for the intended contact conditions.
Hardness selection: Silicone: 20–80 Shore A. The washer geometry needs to correspond with the bottle and closing component as a complete interface.
Custom dimensions: Cut or molded forms can suit different profiles, but the inner diameter, outer footprint and thickness must match the space provided by the actual closure.
Fit & assembly: Place the washer without twisting it and verify that it stays centered as the closure is applied by its intended method.
Use & inspection: Inspect the glass rim and closure seat before fitting, keeping both free of damage and residue.

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.
