Pneumatic/hydraulic cylinder question

Sep 09, 2004 3 Replies

Hello Guys Can I use a pneumatic cylinder as a hydraulic cylinder, as long as the pressure rating of the cylinder is not exceeded ? Will the internal seals hold up to oil ? Thanks... imma



Hydraulic oil makes excellent paint stripper and your seals may suffer, could you use something less corrosive such as mineral oil/water?

But not ethylene glycol, a suspected carcinogen. Propylene glycol is more friendly, but you have to be specific on asking for it, because most "glycol" is still ethylene glycol.
