20mm Silicone Vial Stopper
Rubber stoppers come in all kinds of shapes, sizes and types, and it all depends on where and what they are used for. We have been manufacturing rubber stoppers, as well as other kinds of rubber products, for a really long time now, and we are pleased to say that we now sport an extensive catalogue of rubber products and components, including some of the most commonly used stoppers on the market. As you probably know, a rubber stopper is used to seal a hole, whether inside of a panel or perhaps inside of a machine or a contraption of some kind. However, a rubber stopper can also be used to seal a vial. For instance, a 20mm silicone vial stopper is used to seal and plug 20mm vials. Considering its size, a 20mm silicone vial stopper is only appropriate for vial openings of 20mm and for none other. If you would like to plug a different sized vial, you would need a smaller or larger vial stopper, depending on the vial size.
Vial stoppers are usually made from different kinds of rubber, but the 20mm silicone vial stopper, as you can tell from the name, is made from silicone. Silicone is the perfect rubber material for the manufacturing of vial stoppers. Not only is silicone transparent, so in the case of non-see-through vials, you can take a look at the contents inside of the vial, but it is also a very durable, long-lasting, high-quality rubber material. Silicone is also excellent for vial-sealing use because it has low thermal and chemical conductivity and reactivity, so it can safely store whatever it is that is inside of the vial. It is also non-toxic, so it won’t contaminate the contents of the vial. It is water-repellant, inhibits microbial growth, and is also very resistant to oxygen, ozone, UV lighting, and it can withstand high temperatures.

Discuss Your RequirementsProduct specifications
- Product form
- Vial or bottle closure matched to its neck finish
- Material
- Silicone. Specify the compound grade for the selected service.
- Application focus
- Vials. Size the part against the selected assembly.
- Dimensions to confirm
- Vial neck bore, sealing flange, plug depth and any crimp-cap interface. Match these to vials.
- Nominal size reference
- 20mm. Identify what each nominal value measures and confirm all mating dimensions and tolerances.
- Contact conditions
- Water and oxygen: define concentration, temperature and contact time, then check compatibility with the chosen compound.
- Exposure to evaluate
- Sunlight or UV and ozone. Validate the selected material under the combined conditions.
- Seating check
- Check the sealing contact around the opening and the force needed for insertion and removal.
