Choosing a seal material for Hydraulic Fluids, Polyglycol0water Emulsions Hfc

The table above rates every common O-ring elastomer for service in Hydraulic Fluids, Polyglycol0water Emulsions Hfc on an A–D scale. A is Excellent, B is Good, C is Fair (test before relying on it), and D is Not Recommended. An X indicates insufficient published data.

For Hydraulic Fluids, Polyglycol0water Emulsions Hfc, the strongest candidates are Nitrile (Buna-N), Hydrogenated Nitrile, Fluorocarbon (Viton), Perfluoroelastomer, Ethylene Propylene, Silicone, Fluorosilicone, Neoprene (Chloroprene), Natural Rubber, Styrene Butadiene, Butyl. These ratings are representative at ambient conditions (~20°C). Compatibility shifts with temperature, concentration, pressure and exposure time, so always validate the material against your real operating envelope before committing to a design.
