flexible silicone bottle stopper

One of the products you can find in our company’s offer is a flexible silicone bottle stopper that can be of great benefit to both in the chemical and food industries. But of course, bottle stoppers can be a useful addition to any home. Call us and our experts will explain in more detail what types of flexible silicone bottle stopper we have and what dimensions and design of the stopper would best fit your needs. We make stoppers of different shapes and colors, so you will surely be able to find the type that is most practical for you and has aesthetic properties to your liking.

In case you haven’t heard of the bottle stopper so far, we want to briefly explain why this product can be life-changing. These are stoppers that allow you to seal the bottle after removing the original cap. Unlike lids and caps, you can insert a flexible silicone bottle stopper completely into the opening of the bottle and ensure that it is optimally sealed. The goal of our rubber stoppers is to prevent the contents of the bottle from spilling or losing their organoleptic properties, which would inevitably occur if it is in direct contact with oxygen. Hermetic closure with a flexible silicone bottle stopper ensures that the contents are maximally protected.

The reason why our flexible silicone bottle stopper is made of this material is that silicone is inert, so it does not react chemically with the contents of the bottle. This feature is especially important when it comes to the food and chemical industry. Our stoppers are made of food grade material, which means that their use ensures that the quality of food remains unchanged, that is, that there are no undesirable reactions that would lead to reduced quality of the final product. With our flexible silicone bottle stoppers you can be sure that your products will be optimally protected from external influences, as well as that their quality will be completely preserved.

Stopper & Plug Size Catalog

Compare four stopper profiles and check the selected part dimensions against your opening and available depth. Each profile has its own drawing and dimension meanings.

RST T-Shaped Plugs
