Why Modern Hydraulic Hoses Don’t Last Like They Used To:
We often hear “Old Timers” complain that Hydraulic Hoses just don’t last long like they use to back in the day. Why is this? There is a good chance you won’t find the answer with an AI Search online. You will of course find generic answers like increased pressures, increased UV or any other number of explanations.
Here is something to consider that is most likely the real answer...
Up until the early 1980’s Hydraulic Hose manufacturing used a Lead Curing process. Lead is no longer considered environmentally friendly. One reason lead was used in the rubber curing process was that it made the rubber more durable. This sounds like the most logical reason why Hydraulic Hose Assemblies don’t last like in previous years.
