Silicone Stoppers Guide
Silicone stoppers are small, but exceedingly useful items that come in a variety of shapes, sizes, and dimensions. They’re used in a wide range of industries, but find their use in day-to-day applications as well. Seeing as they’re made out of silicone, they can resist extreme temperatures and are void of smell and taste. That makes them excellent for sealing bottles, containers, and flasks. Other than that, they can be used to plug small holes and seal various compartments all around your home.
In manufacturing and biochemical industries, they’re used to seal sensitive and reactive liquids, as well as in tissue culture work. As you can see, silicone stoppers are incredibly versatile, all while being cheap and customizable. You can find them in almost any size, shape, and color, making them even more convenient for various at-home uses. Of course, they’re not all of the same quality, so be careful when choosing a supplier. If your list of requirements is exceedingly high, we recommend asking for samples before making any sizeable orders.
In most cases, ordering them in bulk is the best possible option out there, especially if you know you’ll need more than just a few of them. Bulk purchases are a great way for you to get your silicone stoppers for as cheap as possible. Naturally, if you need only a couple of them, you can still get high-quality silicone stoppers for a low price, especially if you choose your suppliers carefully. We suggest you read up on product reviews to find out all the available information before you make your purchase.
Overall, silicone stoppers are versatile, sturdy, and food-safe items you can use to seal various containers or even holes depending on their size and shape. You can order them in bulk or as separate items. Whatever the case, we’re certain you’ll find a good use for them extremely quickly, considering their versatility and usefulness.
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.
