Choosing the Right 22mm Circuit Tubing: Key Factors to Consider


Selecting the right circuit tubing is crucial in many industries that require precise fluid management and transport. This article aims to provide insights on the key factors to consider when choosing 22mm circuit tubing. By understanding these factors, businesses can ensure optimal performance, durability, and cost-effectiveness.

1. Material Composition

The first and foremost consideration when selecting 22mm circuit tubing is the material composition. Different industries may require different materials based on their specific needs. Some common materials used for circuit tubing include PVC, polyurethane, silicone, and fluoropolymers. PVC is cost-effective, durable, and has good resistance to chemicals, making it suitable for various industries. Polyurethane is abrasion-resistant and flexible, while silicone offers excellent temperature resistance. Fluoropolymers like PTFE provide exceptional chemical resistance and purity. Understanding the compatibility of the tubing material with the fluid or gas being transported is crucial to avoid any contamination or reactivity.

2. Temperature and Pressure Requirements

Another vital factor to consider is the temperature and pressure requirements of the application. Different tubing materials have varying temperature and pressure limits. PVC tubing, for example, has lower temperature and pressure tolerances compared to silicone or fluoropolymer tubing. If the application involves high-temperature fluids or high-pressure environments, it is essential to select tubing materials that can withstand these conditions to maintain the integrity of the circuit.

3. Flexibility and Bend Radius

The flexibility and bend radius of the circuit tubing are critical considerations, especially in applications that require tight turns or bending. The flexibility of the tubing affects its ability to be routed through complex systems without kinking or collapsing. Some materials like PVC may have limited flexibility compared to polyurethane or silicone, which can be beneficial in applications that involve frequent bending or routing around obstacles. Assessing the required bend radius and the tubing’s flexibility will help choose the right product that will perform optimally without compromising the system’s efficiency.

4. Chemical Compatibility

Different fluids and gases may have varying chemical compositions and properties. It is crucial to ensure that the selected circuit tubing is chemically compatible with the substance it will come into contact with. Chemical compatibility prevents the tube from degrading, cracking, or reacting with the transported fluid. Consulting chemical compatibility charts provided by manufacturers can help identify suitable tubing materials based on the chemical resistance required.

5. Sterility and Cleanliness

In industries such as pharmaceuticals, food processing, or medical applications, sterility and cleanliness are paramount. Choosing circuit tubing that meets strict hygiene standards is crucial to prevent contamination and ensure product safety. Silicone and fluoropolymer tubing are often preferred for these applications due to their high purity and ease of cleaning. It is essential to consider the tubing’s ability to be quickly and thoroughly cleaned, as well as its resistance to microbial growth.

6. Cost Considerations

While performance and quality are essential, cost is also a significant factor to consider when selecting 22mm circuit tubing. The cost of tubing can vary depending on the material, brand, and supplier. It is crucial to balance the desired performance requirements with the available budget. Some materials may be more expensive upfront but offer longer lifespan and reduced maintenance costs, making them more cost-effective in the long run.


Choosing the right 22mm circuit tubing involves considering various key factors such as material composition, temperature and pressure requirements, flexibility, chemical compatibility, sterility, cleanliness, and cost considerations. By carefully assessing these factors, businesses can select tubing that meets their specific needs, ensuring optimal performance, durability, and cost-effectiveness in fluid management and transport applications.
