Silicone Hose Technical Data
The most common uses for silicone hoses are in hot or cold air systems and heating or cooling systems.
Why choose silicone?
Silicone is a resilient material and can withstand extreme environments; operating temperatures are between -60°C and 180°C. Silicone hose is suitable for the transport of air, water, anti-freeze solution, corrosion inhibitor and many other fluids. Silicone will not deteriorate from oil or fuel splashing, however it must be fluorosilicone lined to make the hose suitable for carrying oil or fuel.
What are the different types of silicone?
Our mainstream products are constructed of 3 or 4 plies of fabric reinforced silicone according to operational temperatures and application requirements.
- Polyester fabric reinforced hoses (Standard Hose) are used when the hose is to carry water or air where the temperatures are between -60°C and 180°C
- Nomex fabric reinforced hoses (High Temp Hose) are used for turbo charges with a boost temperature range of -60°C to 230°C
- Flurosilicones (Fuel & Oil Hose) are used to line the hoses to satisfy the increasing demands of enclosed breather systems
What are superflex silicone hoses?
Our superflex hoses consist of an integral silicone liner, 3 plys of polyester reinforced silicone, a 1.2mm thick galvanised steel wire helix running inside the wall of the hose and a convoluted outer. The result is a supremely flexible hose suitable for coolant and air applications with all the advantages of silicone such as optimum performance across a temperature range of -60°C to 180°C and resistance to both positive and negative pressures. Superflex hoses can be easily fitted onto applications that may otherwise have required a shaped hose to be supplied. In this situation the superflex hose provides a quick fix solution and eliminates tooling costs. Please note that the uniqueness of the products flexibility begins to dissipate after 38mm.
How do you measure silicone hoses?
Below are the three main types of silicone hose elbows that we manufacture with the dimensions labelled on them:
The leg lengths on our silicone hose elbows are measured from the cut face to the centre line radius. Elbow leg lengths can be supplied to your requirements (made to order) our standard leg lengths range from 102mm to 152mm depending on the internal diameter of the hose. We recommend that you allow at least 20mm - 25mm straight section of hose for clamping.
