Rubber bung, silicone stopper 41/49 mm - with 9 mm hole

The silicone stopper offers very good grip and fit, making it ideal for wine production. It is more durable than traditional rubber stoppers and seals reliably.

Yes, the stopper is made of high-quality, food-grade silicone and is completely tasteless and odorless. It is therefore safe for storing olive oil or other foods.

The stopper is made of high-quality silicone and is very durable. It is easy to clean and is ideal for repeated use in beverage production.

This silicone stopper is high-temperature resistant and suitable for laboratory use. It provides improved adhesion, but pressure resistance in distillation processes strongly depends on the specific conditions. No specific pressure rating is available.

The silicone stopper has a conical shape of 41/49 mm. It fits ideally on openings in this size range, so also on 5-liter balloons with a 40mm opening.

Yes, the silicone stopper is conical in shape with dimensions of 41/49 mm. A bottle opening of 42 mm is thus within the suitable range, and the stopper should fit securely and tightly.

Yes, this silicone stopper is more durable than traditional rubber stoppers and provides a very good seal. It effectively prevents the ingress of air and contaminants, making it ideal for long-term storage of wine.

Yes, the stopper is completely tasteless and odorless, plus food-safe. It can be used without hesitation for vinegar mixtures or other foods without affecting the taste.

The stopper provides a reliable, airtight seal and is food-safe. It can therefore also be used for vacuum preservation of food, as long as the size fits.

Yes, the silicone stopper is more durable than conventional rubber stoppers. It offers better grip, fit, and aging resistance, making it ideal for homemade wine.

The 9mm hole is standardized and designed for most common fermentation bungs or suitable hoses. It ensures a secure and tight fit.

The silicone stopper is completely tasteless and odorless and does not react with the mild acids and alcohols typically found in wine and beverage production.

The 9 mm hole is designed for standard applications. For thinner hoses, additional sealing may be required to ensure absolute tightness. For optimal hold, the hose should be as precise as possible.

Yes, the silicone stopper offers very good grip and fit, which is better than rubber stoppers. When properly inserted, it should remain tight even with moderate shaking.

Yes, the silicone stopper retains its flexibility even at lower temperatures. It is high-temperature resistant, but also maintains its adhesion and fit in the cold cellar areas.

Yes, the silicone stopper is known for its better grip and fit, making it more reliable than rubber stoppers. It should ensure a secure seal even with light shocks.

Yes, this silicone stopper is high-temperature resistant. It retains its shape and function even at high temperatures, such as those that can occur during sterilization.

The silicone stopper is primarily designed for food and alcoholic beverages. While it is robust, we recommend checking the specific chemical resistance for aggressive laboratory chemicals separately.

Yes, the silicone stopper is heat-resistant and can safely be cleaned in the dishwasher. Ensure thorough drying before reuse.

Yes, the silicone stopper is made of food-grade material and is completely tasteless and odorless. It is ideal for optimally sealing and storing homemade liqueurs.
