Klüberfood 4 NH1-46 from Klüber Lubrication is a long-life synthetic hydraulic oil for use in injection molding reservoirs. According to the company, it is the only fully synthetic NSF-H1-registered hydraulic oil approved for use on Husky injection molding equipment. Compared with mineral hydraulic oils, Klüberfood 4 NH1-46 reduces contaminant build-up and valve blockages, resulting in longer oil change intervals and lower operating costs in hydraulic systems, according to the company. Providing good oxidation stability and overall stability at extreme temperatures from -40 to 135°C (-40 to 275°F), Klüberfood 4 NH1-46 offers protection against friction and wear. It is compatible with all materials that are resistant to mineral oil.
