Medium-viscosity PCTFE inert oil. A diaphragm-compressor hydraulic fluid and pump fluid as well as a mechanical seal barrier fluid, it replaces hydrocarbon oils in equipment that compresses or handles reactive gases such as oxygen and chlorine. No flash point (nonflammable). Korea stock available, ready to ship.
