🔹 What Are Rubber Tube Stoppers?
Rubber tube stoppers, also called rubber bungs, are essential sealing components used to close containers such as:
- Laboratory test tubes and flasks
- Bottles and vials
- Industrial tanks and containers
Functionality:
Rubber stoppers seal from the outside, preventing leakage of liquids, gases, or chemicals without displacing the container’s contents. They are made from flexible rubber compounds allowing compression for airtight sealing. Some designs include perforations or holes for tubing connections in laboratory setups.
Key Advantages:
- Prevents leakage of volatile substances
- Protects against contamination
- Supports pressure retention
- Durable and reusable
