🔹 What is a Rubber Tube Stopper?

A rubber tube stopper, also known as a rubber bung, is a high-performance sealing component designed to close containers such as:

• Test tubes, flasks, and beakers in laboratories
• Bottles, vials, and storage containers
• Industrial tanks and pipes

Rubber stoppers provide airtight sealing from the outside without displacing the contents inside. They are made from flexible, chemically resistant rubber compounds that allow compression, ensuring a secure fit.

Perforated stoppers allow tubing to pass through for gas or liquid transfer, commonly used in laboratory experiments, chemical processing, and industrial fluid systems.
