Tips For Knowing When To Replace Hydraulic Hoses And Fittings

When you have a machine with any hydraulic parts, there are going to be times when the hydraulic hoses and fittings need to be replaced. Waiting too long can have the fluid leaking out, so the machine does not work and damaging other components. Here are a few tips to help you understand when it is time to make some replacements.

Be Proactive

When it comes to hydraulic hoses and fittings, it is best to be proactive. Make a regular maintenance schedule and stick to it. Once a month, check all your hoses and fittings. It is even a good idea to replace all hoses every couple of years. When you do replace a hose, look on the lay-line for the manufacturing date. Do not use any hose that was made more than eight years ago; preferably you want something even newer. The rubber in these hoses breaks down over time and only has a life expectancy of 10 years. If you use one that is older than eight years, it will not last the two years before you replace it.

Signs of Trouble

While doing your regular checks, be sure to wait until the machine is off and the hoses are no longer pressurized. Run a piece of cardboard along each hose to check for any leaks or pinholes. You will notice any fluid on the cardboard and save your hands. Here are a few other signs the hose or fitting needs to be replaced.

  • Crushed hose
  • Wire reinforcement showing through the rubber
  • Twisted hose
  • Cracked fitting
  • Corroded fitting

While you do not have to quit using the machine if one of the above is newly noticed and not causing a pressure problem in the hydraulics, you should purchase the new pieces as soon as possible and make swap out the parts as soon as you get them. If the damage to the part is severe, do not use the machine until the parts have been replaced.

If a small hole occurs in one of the hydraulic hoses or a fitting allows the hose to break free, the pressurized fluid can do serious injury to someone in its path. In addition, it can cause damage to the machine by spraying parts with the fluid or to the hydraulic system if it runs dry. Make sure you have all hoses and fittings looked at regularly and replaced at the first sign of trouble.
