Silicone tubing dimensions

Silicone tubing dimensions

Silicone tubing dimensions are very diverse. This involves hundreds of different sizes, some of which differ by only a few millimeters, but we know that even the smallest difference in silicone tubing dimensions can be very important. As silicon tubing is used in almost all industries, the dimensions vary. There is a need for very small silicone tubing that have a diameter of only a few millimeters, but also silicone tubing dimensions can be very large when there is a need for a tubing that looks like a hose.

We have made an effort to cover a wide range of silicon tubing applications and to offer you sizes accordingly, so we expect that most will be able to find the right size on our website. However, as customer have very different demands, it is impossible to have all sizes always available. That is why we leave the possibility to our clients to choose whatever silicone tubing dimensions they want and we will make tubing for them. It is up to you to choose the diameter, length, thickness of the walls and any other size parameter that you think is important to you.

Also, you can choose other tubing features, not just dimensions. We offer various rubber materials such as natural rubber, silicone, neoprene, FKM and many others. Each of these materials has specific characteristics. FKM and silicone best withstand extremely high temperatures, natural rubber is very durable and resistant to tear and so on. Along with the choice of material, comes the choice of whether you want rigid or flexible tubing. Rigid tubing is usually used when the tubing is installed somewhere long term, while flexible tubing is suitable for moving. Silicon tubing can also be reinforced to improve the tear resistance of silicone, which is otherwise inferior to other types of rubber.
