7mm silicone stopper
7mm silicone stopper the 7mm silicone stopper is one of the stoppers you will come across most often. Both the size and the material from which this stopper is made are ideal for use in many places. The 7mm silicone stopper can be equally needed in the chemical industry, laboratory, food industry and in your household. 7mm refers to the diameter, and you should know that rubber stoppers can generally be irregular in shape, which means that then there are more than one size that matters. You can conclude this based on several factors, and we can give you tips for everything you need to make it easier for you to choose the right size silicone stopper.
And why silicone, when you know that there are other rubber materials on the market and in our country, such as Buna-N, FKM, Ethylene Propylene Diene Monomer (EPDM) and so on? The answer lies in several very important characteristics of silicone that make it ideal for a wide range of purposes. Silicone can be exposed to water, petroleum fluids and many other substances. It already qualifies him for many places. In addition, it withstands temperature ranges of almost 400 degrees. The silicone stopper can operate equally successfully at almost minus 100 and at almost plus 300 degrees C. This is such a large temperature range, that it is unlikely that you will have the opportunity to expose it to higher or lower temperatures than those.
The FDA has approved a special food grade silicone for contact with food and other things that a person will consume. This way you are sure that the 7mm silicone stopper will not negatively affect the product in any way. All these characteristics, as well as many others, make silicone one of the materials that customers most often order from us when they want to buy stoppers.
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
- Material
- Silicone. Specify the compound grade for the selected service.
- Application focus
- Laboratory vessels. Size the part against the selected assembly.
- Dimensions to confirm
- Opening diameter, closure profile, insertion depth and exposed grip. Match these to laboratory vessels.
- Nominal size reference
- 7mm. Identify what each nominal value measures and confirm all mating dimensions and tolerances.
- Contact conditions
- Food ingredients and water: 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.
