Low durometer silicone tubing

Low durometer silicone tubing

The silicone tubing we offer has a wide range of uses and applications, which is why it is commonly used across various industries, that ranges from aerospace to the medical industry. However, if our clients want to guarantee that they opt for suitable silicone tubing, they must ensure that they match the tubing characteristics to the application’s needs. After all, there are different things that can affect the silicone tubing’s performance, and one of the most significant things to check is the hardness, or as it’s more commonly referred to as the durometer. The durability of silicone tubing is the material’s ability to resist pressure and compression.

For substances like silicone, the hardness is measured by performing a Shore durometer test. This will estimate the extent of the object pushed into the material, and if it goes deep into the material, it will have a low rate on the Shore range. If our clients require low durometer silicone tubing, there are a few things that they could do to ensure this. In most cases, low durometer silicone tubing will have a Shore A tag, which means that it is softer than, for example, Shore D tubing that is stronger than other options. So, if our clients require softer tubing for simpler or more delicate applications, they must choose Shore A low durometer silicone tubing that will suit their application needs.

It is worth mentioning that, even though our low durometer silicone tubing is softer than some other tubing that we offer on our website, it is still resistant to a wide range of things. For starters, it won’t be influenced by the weather, meaning that it can be used in both outdoor and indoor settings. Additionally, ozone, UV light, and pressure won’t damage it over a period of time, something that ensures that our tubing can be used longer.
