Silicone vs Rubber Hose – Which Is Best?
When it comes to the hoses that you choose for use in your vehicle, there’s an important choice to be made between silicone rubber and other rubbers, such as EPDM or natural rubber. Each offers its own specific advantages, so which is best? Let’s compare.
Benefits of Silicone Hoses
A silicone hose is able to withstand a greater range of temperatures than rubber. This makes it ideal for those building a racing vehicle or adding a turbocharger to their vehicle. In fact, some silicone hoses can withstand liquid temperatures of up to 300 degrees Celsius.
Noise and Vibration Reduction
Rubber can be a source of noise in the vehicle due to the friction it causes, whilst silicone can actually reduce vibration and sounds.
Silicon as Inert Material
Unlike rubber, silicon is an inert material. This means it won’t bond to surrounding areas such as other pipes or stems. Not bonding to the fittings also means that silicon pipes are easier to remove and refit or to fit new ones.
Can Be Bought in a Range of Colours
Some silicone hoses are available in a range of colours which can make a statement under the hood. A good Silicone Hose Manufacturer such as https://www.goodflexrubber.com/pages/silicone-hose-manufacture will be able to offer a great selection of bold-coloured hosing.
Flexibility and Lifespan
Silicone is a more flexible material than rubber. Both materials start life flexible, but rubber’s flexibility reduces over time, whilst silicone’s flexibility is sustained over time. Silicone also doesn’t break down as quickly as rubber, again giving it a longer lifespan in general. Some say that silicone lasts so long it will frequently outlive the vehicle it is used in.
Benefits of Rubber
For Oil or Fuel
Rubber hoses are considered better for carrying oil and fuel. This is because the molecular structure of silicone simply doesn’t suit these liquids.
For Everyday Cars
Because rubber hoses have fewer slow leaks than silicone (water vapour escapes slowly over time from silicone), rubber can be a better option than silicone for everyday cars.
As you can see, silicone hoses offer many superior benefits. Being able to withstand higher temperatures and reduce noise make them ideal for racing cars. However, when it comes to fuel, oil and everyday driving, rubber may have the edge.a
