I have a number of molding machines with hoses that leak oil (a.k.a. sweat/weep). Not spraying, or at the fitting, it can be anywhere along the hose, no particular size of hose or location, it is enough oil to drip off the hose. I first noticed it with the O.E.M. hoses, so I have tried 2 different brands and noticed the weeping with in 6 mos. I use DTE 25 oil (46 weight) at 100 degrees F. pressure is no more than 250 bar. We run radial piston pumps from Moog and Mobil oil. Does any one have an idea why this happens or have you seen it before?
