Product description
Conical rubber stoppers in the widest selection of sizes - a practical seal for winemakers, laboratories and technical needs. We sell them by the piece, you choose the specific size in the variant table.
Classic rubber stoppers have a conical (tapered) shape, thanks to which they fit perfectly into openings of various diameters and reliably seal them. 23 different sizes are available - from small stoppers with a diameter of 3.5 / 6.5 mm up to large stoppers 94 / 107 mm.
Each size is described in the table as bottom diameter / top diameter and height in millimetres together with the weight in grams, so you easily find exactly the stopper you need. The material has a specific gravity of 1.52 - 1.58 g/cm³ and a hardness of 45 or 54 °ShA, the working temperature is in the range -25 °C to +70 °C.

Frequently asked questions
How do I choose the right size of stopper?
Measure the diameter of the opening you need to seal, and in the variant table below select the stopper whose dimension (bottom / top diameter) corresponds to your opening. Thanks to the conical shape, the stopper seals within a certain range of diameters.
What do the two dimensions next to each stopper mean?
The first number is the bottom (narrower) diameter and the second number the top (wider) diameter of the conical stopper in millimetres, supplemented by the height and weight of the piece. You seal the opening within the range between these two diameters.
What temperature do the stoppers withstand?
The stated working temperature is -25 °C to +70 °C, which covers common home, winemaking and workshop use.
Details of the dimensional tolerances for rubber products can be found in the shop footer.
