Large diameter soft silicone tubing

Large diameter soft silicone tubing

Our large diameter soft silicone tubing can be used across a wide range of applications and across dozens of industries. The large diameter of our products makes the tubing essential for certain industries such as automotive, shipping, transportation, and more. In addition to that, our products find their use across many niche industries such as communication equipment and aerospace.

With our product, clients are getting silicone tubing with a larger opening being able to transport liquids and gasses on a larger scale. The silicone properties make the tubing more elastic and more flexible. We make our tubing from the finest silicone to enhance these properties. The low thermal conductivity and low chemical reactivity make our product resistant to chemicals and extreme temperatures. Our product can withstand temperatures from -100 to +250 degrees C.

Other properties of our large diameter soft silicone tubing include water resistance, anti-stick, resistance to UV lights, and more. Also, silicone is a material that offers excellent electrical insulation, and our product is no different from that. Due to our product’s excellent resistance to electricity, it opens a wide range of applications and uses. Due to all of these properties, our silicone tubing is much more flexible and can be used across many more industries where these properties are needed. Thanks to the need to design silicone tubing with a larger diameter, our large diameter soft silicone tubing will work well across hundreds of applications and uses. 

Since the size is important to our clients, we have a size chart for you to look at and determine what size best works for you. If you’re having trouble doing just that, then you can get in contact with us and we will help you make the correct decision. We make our large diameter soft silicone tubing in various sizes and shapes so that every client can find a product that suits their needs.
