Radiator hoses
How are radiator hoses constructed?
Radiator hoses are constructed with three layers:
- inner - is made of different types of rubber (e.g. EPDM) and is characterised by its resistance to heat and coolants;
- reinforcement - which takes the form of a synthetic cord and/or steel spiral to increase the pressure/vacuum resistance of the hose;
- outer - also takes the form of various types of rubber and provides resistance to external agents, ageing, and heat (in some cases it is also oil resistant).
As far as the production material is concerned, radiator hoses are almost exclusively made from synthetic rubber compounds. These are mainly EPDM, NBR, SBR, and CR. Rubber provides the hoses with a high degree of resistance to extreme coolant temperatures and is also mechanically and chemically resistant.
It's also worth noting that you'll buy radiator hoses by the metre. Thus, you will choose the right hose length for your needs.
How to choose radiator hoses?
When you are choosing radiator hoses, there are several important points to consider. We briefly describe each of these below.
- Permissible working pressure - Specifies at what pressure the hose can operate. Coolant hoses are usually for low-pressure applications that do not exceed 6 bar.
- Operating temperature range - A very important parameter for cooling systems. Exceeding the temperature limit will lead to a loss of properties of the hose, which may result in damage. Usually, the range is between -40 and 120 degrees Celsius.
- Nominal diameter - This parameter defines the internal diameter of the hose, which has a direct impact on fluid pressure and several other issues.
- Vacuum resistance - Determines whether radiator hoses are resistant to suction power. To do so, they should have spiral reinforcement.
- Minimum bending radius - Demonstrates the flexibility of the hose. Indicates the point below which the hose cannot be bent, as this will result in damage (e.g. breakage).
- Manufacturing material - Directly translates into the properties of the hose (e.g. permissible temperature range or oil resistance).
When you take all of the above into account, you are sure to make an effective choice of rubber radiator hose.
FAQ
What is a radiator hose used for?
A radiator hose is used to transport antifreeze in industrial installations as well as in the engines of various vehicles. It is characterised by its resistance to ethylene glycol, which is one of the main components of this type of medium.
Does the size of the radiator hose matter?
Yes, the size of the radiator hose does matter. The larger the diameter of the hose, the lower the fluid pressure will be. In turn, the lower the pressure, the lower the boiling point of the fluid. However, in most cases you will be selecting the diameter of the hose according to your specific industrial installation.
Which is indicated by hard radiator hoses?
Hard radiator hoses can be an indication of its poor condition. The hose should feel solid to the touch, but not hard, spongy or soft. Sometimes it happens that a hose is hard along its entire length, but has a soft spot. It is then also due for replacement.
