Re: Where to get miniature hydraulics? OR...

What about using a food-grade medium, like glycerine? That would very likely be safe for the seals in a standard aluminum & stainless piston. Or to be absolutely sure, use it with a food-grade piston, with nylon or delrin end caps and stainless body; those seals have to be especially nonreactive.

Re: Where to get miniature hydraulics? OR...

you could always find out what the seal in pneumatics is made of then see if the material is "edible" by the fluid
