6.5 silicone stopper solid
6.5 silicone stopper solid is one of the most versatile versions of silicon stoppers and rubber stoppers in general. Rubber and silicone stoppers have a very broad purpose, and we will mention some of the main purposes of the 6.5 silicone stopper solid. Stoppers are generally needed everywhere. Whether you work in a lab, produce food and drinks, or a 6.5 silicone stopper solid is needed for a completely different industry, stoppers are always needed.
Silicone stoppers have an even more diverse application than stoppers made from other types of rubber. In addition to silicone, other types of rubber are available if you order from us, such as natural rubber and neoprene, and silicone is the most sought-after material. There are several reasons for the popularity of silicone. It is a material that can withstand very high temperatures, so it can withstand up to 300 degrees Celsius. Also, the silicone stopper can be exposed to low temperatures. Another very important reason is that there is food grade silicone, and there are many times when a silicone stopper can come in contact with food. That is why the use of silicone is ideal in this case, because food grade silicone means that the quality and safety of food and other similar things will not be compromised.
Silicone is usually transparent, but can be any color you need. If you need different colors, for example for laboratory use, we will do it for you. Also, if you need any more advice from us about 6.5 silicone stopper solid, you can contact us. This includes size tips too. A stopper with a diameter of 6.5 mm is very often used, but if this size does not suit you, you can order a custom one. Also, the diameter can remain 6.5 mm, but with a change in thickness for example.
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
- Solid, unbored container stopper
- 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.
- Closure section
- Closed, unbored section; define the sealing profile and the insertion stop.
- 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.
- Nominal reference
- The body describes a 6.5 mm diameter. Identify which face or section it measures and confirm the other diameters and height on the drawing.
