Choosing a seal material for Sf 1147 Ge Silicone Fluid

The table above rates every common O-ring elastomer for service in Sf 1147 Ge Silicone Fluid 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 Sf 1147 Ge Silicone Fluid, the strongest candidates are Nitrile (Buna-N), Hydrogenated Nitrile, Fluorocarbon (Viton), Perfluoroelastomer. 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.
