How long do hydraulic hose assemblies last? There is no answer to how long you should wait before replacing hose assemblies on your equipment. The good news is that there are signs that you can look for to determine when it’s time for preventive hose assembly replacement.
Do not use a old or worn hose assembly on your equipment.
The Society of Automotive Engineers (SAE), proclaims the shelf life of bulk rubber hose is 10 years from the date it was manufactured. The manufactured date should be located on the layline of the hose. If its close to 10 years. It shouldn’t be used. The purchase of a new hose assembly is by far less expensive than the clean up and potential harm and injury if an old hose breaks or blows.
Make and follow a regular preventative hose maintenance schedule.
For most assemblies, a visual inspection once every 30 days and replacement of assemblies every year or two is adequate. Eighty percent of blown hoses are caused by external damage through kinking, crushing, or abrasion of the hose and can normally be seen by just a quick look.
Keep a log of the hose replacements, especially replaced hose failures. You can use this log to estimate how long your hoses may last in your equipment. But nothing will replace a visual inspection.
Critical hose assemblies should be replaced more often as these will cause the most damage if blown. Critical assemblies may be those that are close to the operators or failure could result in injury or would cost a great amount of damage.
Replace your assemblies if you see oil leaking around fittings or along the hose, crushed hoses, abrasion or any exposed wire is a sure sign of need for replacement, any significant damage to the outer cover, twisted hoses, Kinks, cracked, rusted, or corroded fittings.
