rubber silicone stopper
Whether you work in the chemical industry or you are a housewife who wants to optimize your home, rubber silicone stopper is a tool that can be useful to you. This object has a conical shape and is a seal that ensures the hermetic closure of various openings. These openings can be openings on bottles, various utensils you have in your kitchen, but also openings on laboratory utensils. Unlike lids and caps, rubber silicone stoppers not only achieve partial closure of bottles and other objects, but also hermetically close them and thus provide protection from various external conditions, such as oxygen, microorganisms, UV rays, and more. .
Our company manufactures items such as rubber silicone stoppers and offers a huge selection of colors, shapes, sizes and designs. You need to decide which features best suit the final application, and then call us and make your order. Of course, if you are confused and not sure which rubber silicone stopper would be the best fit for your needs, you can always consult with our experts who will help you find exactly what you need.
The reason why we make rubber silicone stoppers is because this material offers many advantages over materials such as plastic, wood and metal. Rubber silicone is a very resistant material that does not change even in extreme conditions, which means that you can be sure that it will surely fulfill its purpose, and do it for a long time. Secondly, this material is very chemically inert, which means that it does not react chemically with a large number of substances. This is important both for the food industry, where it is important that the material does not react with food, so as not to lead to potential dangers to the health of consumers, and to the chemical industry. When performing the test, it is important that the plugs do not react with liquids and gases, in order to avoid inaccurate results.
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.
