tapered rubber stoppers
Tapered rubber plugs are one of the most durable and efficient plugs you can find on the market. These are plugs that have practically no expiration date. Even after years of use, its efficiency will be the same. Its conical shape allows complete, hermetic closure of the bottle or container. The material from which this plug is made is high-quality rubber and high durability. Whether you keep certain chemicals, essential or any other oil in the bottle, you can be sure that it is resistant to all these materials. It does not matter whether the contents are hot or cold because the rubber from which the tapered rubber stoppers are made is resistant to temperatures from -40 to 200 degrees C. They are very small, easily portable and weigh only a few grams. You can use them in literally any situation.
You can find tapered rubber plugs of different diameters on the market, they are usually produced without threads, so they are completely flat. Depending on the same use, tapered rubber stoppers filled with one or two holes can be purchased. The holes are small enough to prevent the leakage of liquids or gases or nutrients from the contents to be preserved. Again, the material of the stopper itself is flexible enough that the contents of the bottles or dishes can be easily removed with a pipette or some other means without complete opening.
Such crooked plugs, precisely because of their multi-purpose use, are much used and are much more efficient than classic fasteners. Tapered rubber stoppers are used in many industries, most notably in the food and pharmaceutical industries. They are suitable for the production of wine, juices or sour water in the home. In addition, they are used daily in the kitchen.
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.

Discuss Your RequirementsProduct specifications
- Product form
- Removable closure fitted inside an opening
- Application focus
- Bottle necks and wine bottles. Size the part against the selected assembly.
- Dimensions to confirm
- Opening diameter, closure profile, insertion depth and exposed grip. Match these to bottle necks.
- Profiles discussed
- Tapered sections. Select the profile that matches the mating part and dimension that section explicitly.
- Contact conditions
- Lubricating oil, other gases, food ingredients, wine and juices: define concentration, temperature and contact time, then check compatibility with the chosen compound.
- Exposure to evaluate
- Oil splash. Validate the selected material under the combined conditions.
- Seating check
- Check the sealing contact around the opening and the force needed for insertion and removal.
