geminYe Inert PFPE Mechanical Pump Oil

geminYe® perfluoropolyether (PFPE) family of lubricants are non-flammable, chemically inert, and thermally stable. geminYe PFPE mechanical fluid oils have excellent lubricity properties and are available in viscosity grades suitable for use in all vacuum pumps. When used with proper filtration, geminYe fluids provide exceptionally long service life. A drop-in replacement and direct equivalent to other PFPE brand vacuum oils, geminYe fluids are completely miscible with Fomblin®, Krytox®, and other brand inert PFPE fluids of the same grade.
