Caring for Hydraulic Hoses

Hoses and couplings differ from one manufacturer to another and might not be interchangeable. Mixing parts from different manufactures could run you the risk of leaks or couplings slipping, which can lead to a detrimental effect on the service life and performance of the machine.

A hydraulic hose is made of 3 parts:

  • The outer wall protects against the weather etc.
  • The reinforcement is to ensure the hose can withstand the pressure
  • The inner tube transfers the fluid

Check for damage

Damaged hoses are dangerous because they can split and damage the machine, and the frayed steel reinforcing can stick through the outer wall and pierce the skin.

Do not use damaged hoses, they could split and damage the operator or the machine.


Correct installation

An important part of caring for hydraulic hoses is ensuring they are installed correctly. When installing a straight line hose, there must be enough play to accommodate pressure distribution to ensure the hose is not too short.

 Ensure all the hoses are secured, especially when being transport even if not in use.  Trailing hoses can get caught whilst moving or the ends can be damaged by dragging on the ground.

Moving parts

Another point to consider when installing is the moving parts of the machine, will it affect the needed length of the hose or could it trap the hose.

Clean the machine to the point where a hose needs to be fitted. This prevents contamination in the hose.

When both ends are connected, allow the oil to flow through at low pressure and check for leaks.  This also ensures that the air is pushed out of the tubes, thus improving performance.

All hydraulic hoses have a limited service life, which can be affected by various factors, such as temperature and handling of the hose.


The main causes of broken hydraulic hoses

  • Misuse – allowing hoses to drape on the ground or rub against tyres etc.
  • Incorrect application – using the wrong type of hose for the situation/fluid
  • Incorrect hose routing – ensure the hose will not get trapped when the machine is moving/folding

Look after your hoses, treat them with care and respect.  Regular maintenance and getting it right first time can save you a lot of money in the long run.
