Reply to "Hydraulic Hose Weeping"

drlMember

We too are having the same problem on our hydraulic equipment. Our hydraulic power unit runs at a pressure of 3000 psi (207 bar) on Mobil DTE 25 and the oil temperature is 45°C and has been in constant operation for the last year (24 hours a day, 7 days a week).

We are using Parker 351TC which has a constant working pressure rating of 4000 psi (275 bar) which leaked after 1 year of use, twice (the hoses were replaced once already).

Did you ever find a solution to the problem?

In our case, the manufacturer Parker suggests switching over to a 575X hose with a nylon inner tube (claims the synthetic rubber inner tube is the cause), but I'm not sure if I believe the reason since the 351TC indicates it is designed for a 'constant' working pressure of 4000 psi.
