Silicone Stopper Clear
Don’t you just hate when you try and do a DIY plumbing job, only to realize that you don’t have a rubber stopper to seal that one little opening? It is in instances like that one that most people begin to appreciate the rubber stoppers and just how valuable and versatile they are. Let’s take a look at a silicone stopper clear. A small transparent product such as this one can be found virtually everywhere. You can find it in the automotive industry, chemical industry, aerospace industry, and many others. Even furniture makers love themselves a silicone stopper clear. But, how is that possible, you might ask?
Well, a silicone stopper can be made in a variety of ways. It comes in all kinds of shapes and sizes. It can be as small as only a few millimetres in diameter and height, and as large as a couple of centimetres in diameter and height. We manufacture both, with everything in between. What we also do is make these in various shapes as well. Silicone stoppers can be cylindrical or half-cone shaped, depending on where they’re used and applied. Some even come with little tabs for easier extraction.
Now, a variety of shapes and sizes is not the only thing that makes these products so popular and versatile. Silicone is naturally very stable and non-reactive. For instance, a silicone stopper is an excellent choice if you need to plug something that resides in a really hot or cold environment because these stoppers are very thermally stable, and they don’t conduct heat nearly as much as some other, similar materials. Silicone stoppers are also non-toxic, and they don’t support microbiological growth, which is precisely why you will often find these in the food industry facilities, alongside clear silicone tubing, plugs, and grommets.
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
- Material
- Silicone. Specify the compound grade for the selected service.
- Dimensions to confirm
- Opening diameter, closure profile, insertion depth and exposed grip.
- Visibility
- Define the required visibility through the finished wall and approve appearance using a sample of the ordered thickness.
- Profiles discussed
- Tapered sections and cylindrical 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.
- Seating check
- Check the sealing contact around the opening and the force needed for insertion and removal.
