Silicone hose FAQs

Hoses in vehicles and other machinery are often used to carry coolants and other liquids. Traditionally, they would have been made of rubber, but today they are more likely to be silicone.

Silicone has a number of advantages in terms of durability and performance that more traditional materials can’t match. Here are some of the most commonly asked questions concerning them.

Why use silicone hoses?

Silicone hoses are durable and perform better than other materials at high temperatures. They can also be produced in a wider range of colours, which gives them greater aesthetic appeal under car bonnets, for example.

Are they easier to work with?

Yes! Silicone hose manufacturers such as will tell you that silicone hoses attach more easily. They are also less likely to become bonded to other parts over time, so they make life easier when you need to remove them.

What type of hose clips should be used?

In order to avoid damage, silicone hoses should always be fastened with clips that have rolled or bevelled edges and a smooth inner surface or liner. Don’t use clips that have the drive mechanism protruding on the inside of the clip.

Can silicone hoses be cut to length?

If the hose is too long for your needs, you can cut it down to size. The best way to do this is to measure carefully, then tighten a clip around the hose at the point you want to cut it. You can then use a sharp craft knife blade to cut, using the edge of the clip as a guide to make sure you keep it straight.

Are there different finishes?

Silicone hoses are available in both standard and glossy finishes. Standard hoses give a fabric-like appearance as they are wrapped in reusable fabric before curing. Glossy hoses are wrapped in cellulose tape before the curing process, giving them a smoother, neater finish. Where performance is essential, you will use a standard hose; where looks also matter, the glossy option is the one to go for.

Can hoses be made to order?

Silicone hoses can be made to order in a wide variety of sizes, colours and finishes. Keep in mind, however, that if you need a hose for which the tooling doesn’t already exist, it is likely to be more expensive.
