p>Vacuum technology is used in various industries, including the medical, food, and electronics industries, among others. One of the essential components of vacuum technology is tubing. Tubing is used in vacuum systems to transport gases, liquids, or solids from one place to another under vacuum conditions.
However, not all tubing is suitable for use in a vacuum. Certain types of tubing are more suitable for use in vacuum systems compared to others. In this article, we will take a closer look at what type of tubing is for vacuum use and what factors should be taken into account when selecting vacuum tubing.
Factors to consider when selecting vacuum tubing
Before we dive into the types of tubing suitable for vacuum use, it is essential to understand the factors that should be considered when selecting vacuum tubing. These factors include:
- Pressure range: The maximum and minimum pressure that the tubing will be exposed to will determine the type of tubing that is required.
- Temperature range: The maximum and minimum temperatures that the tubing will be exposed to will also affect the type of tubing required.
- Chemical resistance: The chemical composition of the substance flowing through the tubing can affect the tubing’s material and durability. Therefore, it is essential to ensure that the tubing is chemically resistant to the substance being transported.
- Gas permeability: The tubing’s gas permeability is important when transporting gases for analysis, as gas permeable tubing may result in inaccurate readings.
- Flexibility and rigidity: The tubing’s flexibility and rigidity are essential in determining the tubing’s bend radius and ability to withstand pressure changes.
Types of tubing for vacuum use
Now that we understand the factors to consider when selecting vacuum tubing, let’s take a look at the types of tubing suitable for vacuum use.
1. Stainless steel tubing
Stainless steel tubing is ideal for vacuum use because it is highly durable and can withstand high temperatures and pressure changes. It is also highly resistant to chemical corrosion, making it suitable for transporting a wide range of substances.
2. PTFE tubing
PTFE tubing is another commonly used tubing for vacuum systems. It is highly resistant to chemical corrosion and can withstand high temperatures and pressure changes. However, it is not as durable as stainless steel tubing and can be prone to cracking and splitting.
3. Glass tubing
Glass tubing is an excellent choice for vacuum systems that require optical monitoring because it is highly transparent. It is also highly resistant to chemical corrosion and can withstand high temperatures and pressure changes. However, glass tubing is relatively fragile and can be challenging to bend and shape.
4. Silicone tubing
Silicone tubing is highly flexible and can withstand high temperatures and pressure changes. It is also highly resistant to chemical corrosion, making it suitable for transporting a wide range of substances. However, it is not as durable as stainless steel tubing and can be prone to tearing and puncturing.
5. Polypropylene tubing
Polypropylene tubing is highly flexible and can withstand high temperatures and pressure changes. It is also highly resistant to chemical corrosion and can be used to transport a wide range of substances. However, it is not as durable as stainless steel tubing and can be prone to cracking and splitting.
Conclusion
In conclusion, selecting the right tubing for vacuum use is crucial to the efficiency and performance of vacuum systems. Factors such as pressure range, temperature range, chemical resistance, gas permeability, flexibility, and rigidity must be considered when selecting vacuum tubing. The five types of tubing suitable for vacuum use are stainless steel tubing, PTFE tubing, glass tubing, silicone tubing, and polypropylene tubing. Each type of tubing has its advantages and disadvantages, and the appropriate tubing should be selected based on the specific needs of the vacuum system.

Frequently Asked Questions about Tubing for Vacuum Use
What is tubing for vacuum use?
Tubing for vacuum use is a specialized type of tubing that is designed to withstand the high vacuum pressures commonly encountered in scientific and industrial applications. This tubing is typically made from materials with low outgassing rates and high chemical resistance.
What types of tubing are available for vacuum use?
There are three main types of tubing that are commonly used for vacuum applications: metal tubing, plastic tubing, and rubber tubing. Metal tubing is the most durable and can withstand the highest temperatures and pressures, while plastic and rubber tubing are more flexible and easier to work with.
How do I select the right tubing for my vacuum application?
Selecting the right tubing for your vacuum application depends on a number of factors, including the required vacuum pressure, the temperature of the environment, the type of gas or fluid being transported, and the level of chemical resistance required. It is important to consult with a knowledgeable supplier who can help you select the right tubing for your specific needs.
Can I use regular tubing for vacuum applications?
No, regular tubing is not suitable for vacuum applications as it is not designed to withstand the high pressures encountered in these environments. Attempting to use regular tubing for vacuum applications can result in leaks, damage to the tubing, and potential safety hazards. It is important to use tubing that is specifically designed for vacuum use to ensure the safety and effectiveness of your system.
