Hydraulic Hose Assemblies: When is it Time to Repair or Replace?

How long can you expect your hydraulic hose assemblies to last before they need to be replaced or undergo some type of repair? As with any type of maintenance work, there isn’t a clear answer to this question. Fortunately, however, there are some clear signs that can be recognised in order to identify when it’s time to make a repair so that you can avoid a replacement. Let’s explore the options:

Replace any worn or aged hose assemblies used on equipment

According to most engineers, a rubber hose can last for 10 years from its manufacture date. This date is most often printed on the hose itself. If it’s more than or close to the 10 year mark, then it should not be used. Buying a new hose assembly is far more cost effective than needing to fix the potentially dangerous and costly results from a blown or broken hose.

Develop and follow a maintenance schedule for hose maintenance

It’s recommended that hose assemblies undergo a visual inspection every month with a full replacement of them every 12-24 months. Kinking, abrasion or crushing is the cause of 80% of all blown hoses and this can be prevented by taking a quick look at the condition of them.

As part of the maintenance schedule, it’s a smart idea to keep a detailed record of all hydraulic hose assembly replacements and failures. This can then be referred to in order to establish an estimate of what to expect and when to replace etc. However, nothing compares to the protection that can be gained from regular visual inspections.

When it comes to hose assemblies that are critical to the functioning and operator safety of equipment, they should be replaced on a more frequent schedule.

Hose assemblies should also be replaced if any leaking oil is seen close to fittings or if there is any abrasion, crushed or cracked hoses found. You should also look for exposed wires and corroded fittings.

In summary, visual inspection is key and following a maintenance schedule can go a long way to prevent breakages and other blow out incidents.
