Silicone tapered bottle stopper
When we think about bottles, we usually envision bottles with long necks that are with the same width from the opening up to the main widening where the bottle starts. However, not all units are made this way, and the tapered bottles are used in many different places including laboratories and even the food and beverage industry.
These models don’t come with the same neck width everywhere, and it is not perfectly cylindrical. The next of the unit gradually changes and it can become smaller or bigger depending on the type of product that you use. When we try to seal these openings, we may realize that the standard plugs may not do a proper job, and we need to use a silicone tapered bottle stopper. The difference between this type and every other plug is that the tapered bottle stopper is going to help you make a tight seal and prevent anything from spilling from the bottle, or air, moisture, or anything else from penetrating inside it. They are an extremely popular option and as you already know, silicone can be reused and it can be easily cleaned and disinfected so it does not transfer molecules from the previous container to the next one.
We can help you choose the right type of silicone tapered bottle stopper for your needs, and as manufacturers, we are able to provide a variety of options, as well as customize them depending on your needs. The silicone tapered bottle stopper is extremely practical, long-lasting, and reliable, and no matter where you use it, you won’t have to utilize any specific tools to be able to install or remove it. Just make sure that the container, as well as the opening and the silicone tapered bottle stopper are clean and dry before you push it in the hole so that there won’t be any dust particles that could break the seal.
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.
