silicone cork stopper
Looking for a silicone cork stopper with features that perfectly fit your needs? We are happy to let you know that you are in the right place, because in our company you can find what you are looking for. We are manufacturers of silicone cork stoppers that can play a variety of practical roles. Therefore, we wanted to offer stoppers of various colors, sizes, shapes and styles, so that everyone can find the optimal stoppers for their needs. You just need to clearly define what kind of stoppers you need, and we are here to provide you with products of the desired quality.
However, if you are not familiar with these items, we want to explain to you why silicone cork stopper can be a useful addition to your home, or even your workplace if you work in a food or chemical laboratory. These objects are closures that achieve hermetic closure, due to the fact that they have a conical shape and can be placed inside a particular opening. They have suitable properties, which means that they do not react chemically with the container or its contents. This can be a useful accessory for any kitchen, as it allows you to hermetically seal those bottles whose original cork you have lost or you simply cannot achieve hermetic closure with. Instead of letting the food spoil, install a silicone cork stopper and make sure the liquid or food stays fresh for a long time.
These items can also be of great importance in the chemical industry, as they enable the hermetic closure of laboratory vessels and achieve an optimal chemical reaction. What this material provides is inertness, which means that it will not react with the contents of the test tube or cup under any circumstances. And this gives you confidence that the reaction will be performed in the best way and that you will get exact results of the experiment.
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
Match stem diameter A, flange diameter B, stem length C and flange thickness D. E refers to the underside recess; use the selected row and approved drawing to confirm the actual profile.
RSA Tapered Corks
Compare large-end diameter A, small-end diameter B and Height, in mm. The mating bore and required seating depth determine where the taper contacts the opening.
RSB Undercut Plugs
Compare neck diameter A, flange diameter B, flange-to-lip distance C and flange thickness D. Check panel thickness and rear clearance. E refers to the underside recess.
RSD T-Shaped Stoppers
Compare stem diameter A, flange diameter B, stem length C and head thickness D, in mm. Check the seating surface and available depth as well as the hole diameter.
