Advantages of Silicone Hose

Advantages of Silicone Hose

- Which is better?

Silicone hoses are the preferred hose type when it comes to the automotive industry as they offer a number of benefits over the traditional rubber hose.  The main benefits associated with Silicone Hose are:


[1]  Temperature Resistance

Silicone hoses have a much greater temperature resistance compared to rubber hoses.  They will perform much better in conditions of temperature extreme are suitable for use across a temperature range of -60 to +180 Degrees Celsius.

[2] Flexibility

Silicone hose is more flexible than rubber hose and is therefore preferable when it comes to a job.  More importantly it retains this flexibility over its life-cycle unlike rubber that becomes hardened and brittle with time.


Silicone hoses have a greater life expectancy compared to traditional rubber hoses due to their inherent heat ageing resilience.  Over prolonged periods of time high rubber sustains what is called heat ageing damage.  This damage occurs under the bonnet of a vehicle under normal driving conditions.  The results of this damage causes rubber hoses to become stiff, crack and fail at their job.  Silicone hoses have an excellent heat ageing resistance and remain in excellent working order for years.



Silicone hoses are mush easier to work with than rubber hoses.  Simple installation jobs can be completed quickly and easily with silicone hoses.  Rubber hose can be very difficult to remove as it has a tendency to bond with fittings over time.  Silicone will not 'stick' to your radiator in the same way that rubber will.

[5] Chemical & Corrosion Resistance

Silicone hoses also demonstrate an increased resistance to chemicals such as coolant.  Compared to rubber silicone hose structure displays greater physical integrity when it comes into contact with common garage chemicals such as coolant.


[6] Noise & Vibration

Silicone has an inherent physical property that allows it to absorb vibration and dampen noise above and beyond that of rubber.  The point at which rubber is mated to another surface is well known for causing unwanted noises and vibration.  For a smoother, quieter engine - silicone is a better choice.

[7] Weather Resistance

Silicone demonstrates better weather resistance than that of rubber.  This is an important choice if you are living in a climate with challenging environmental conditions such as rain and humidity.  Silicone will stand up better to the tests of time when the weather is a factor to be considered.


Silicone just looks a whole lot better than rubber.  It has a visually pleasing gleaming finish and it most importantly is readily available in a range of colours.  If you want to jazz up the look of your engine, switch to silicone tubing on your next tubing re-fit!
