Vacuum Tubing
Product Code : EL-LI-10780
Quick answer: Vacuum tubing is thick-walled flexible tubing that links a vacuum pump or water aspirator to filter flasks, desiccators and other glassware. This polymer blend tubing has an 8 mm bore, a 6 mm wall, a square outer profile and a -50 to 200 °C rating. Lab Exports manufactures it in Delhi for school, college, research and industrial laboratories.

How vacuum tubing is used
In a vacuum line the tubing has to carry a pressure difference of close to one atmosphere without collapsing. That is why vacuum tubing has a much thicker wall than ordinary rubber tubing: the 6 mm wall of this tubing, around an 8 mm bore, keeps the passage open while the pump draws air out of a Buchner flask, desiccator or distillation set-up.
The polymer blend is offered as a longer-lasting, UV-resistant replacement for natural rubber vacuum tubing, which tends to harden and crack with age and light exposure. The square outer profile lets a run of tubing lie flat on the bench instead of rolling.
- Cut the tubing to the length needed with a sharp blade, keeping the end square.
- Push the tubing fully over the hose barb of the pump or aspirator.
- Connect the other end to the side arm of the filter flask, desiccator or trap.
- Check the joints for leaks before starting filtration or evacuation.

Frequently asked questions
What size is this vacuum tubing?
It has an 8 mm internal diameter and a 6 mm wall thickness.
Why is vacuum tubing thicker than ordinary rubber tubing?
A thin-walled tube is squeezed flat by atmospheric pressure when air is pumped out of it. The heavy 6 mm wall resists that collapse and keeps the line open under vacuum.
What temperatures can the tubing handle?
It is rated from -50 °C to 200 °C, and the polymer blend is UV resistant.
What is the price of the vacuum tubing?
