VapCor Inc. introduced HydraFlow NS Hydraulic & Gear Fluids designed to create a safer workplace in environmentally sensitive areas. HydraFlow NS fluids typically have a pour point of -60°F (-51°C) and an upper operating range of approximately 150°F (65°C). This range of usability enables HydraFlow NS fluids to work in most weather conditions. Unlike mineral oil based lubricants HydraFlow NS fluids do not oxidize over time to form sludge. They also do not break down (hydrolyze) in the presence of water a common problem with polyol ester and vegetable based lubricants.
