Tapered rubber plugs
In everyday life, we use many elements that have a certain content that must be protected from external influences. A supplement that helps us preserve many things, such as machines or furniture, is tapered rubber plugs. These plugs are made of a specific material that is abrasion-resistant and is an excellent insulator. It is very flexible and adapts to various conditions and temperatures from extremely low to very high ones. In its material lies the key to its adaptability and usefulness.
The application of tapered rubber plugs is also wide. In addition to home use, it’s used in many industries such as scientific, medical, cosmetic and food. To keep the observation element intact and serve its purpose, tapered rubber plugs perform their protective function. In fact, they are designed to serve by closing a glass container, or some other delicate tool, preventing the contents of the bottle from coming out. At the same time, it protects the contents of a particular tool from external influences such as dirt or climate change. Another great advantage of this plug is the insulation, on which special emphasis is placed when it comes to the chemical industry. During chemical experiments in laboratories, the use of tapered rubber plugs is simply unavoidable. It serves to close the opening of the test tube and thus ensures that the liquid comes out of it or changes its composition.
You can find tapered rubber plugs in various sizes. In this way, they skillfully adapt to all situations and manage to secure the desired items. You can find them in smaller sizes where they are ideal as a bottle cap or smaller openings, to large volumes that are great when working on machines. Its increasing use is in the automotive and electronics industries. Due to their physical properties, they are easy to use and install on all substrates.
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.
Custom colors are available to your Pantone color code. Include the code in your inquiry.
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, laboratory vessels and test tubes. 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
- Food ingredients: define concentration, temperature and contact time, then check compatibility with the chosen compound.
- Exposure to evaluate
- Dust or debris and rubbing or abrasion. 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.
