AMS7287 supersedes the long time specification, AMS-R-83485, for the aerospace industry. Covering a wide variety of gas turbine engine lubricants, higher thermo-oxidative tability (HTS) lubricants like Mil-PRF-23699 (HTS), Mil-PRF-7808 Grade 4 and AS5780 Class HPC, as well as a variety of jet fuels, the specification demands a material with superior chemical resistance. With respect to temperature, AMS7287 also calls for a thermally stable compound, for seal functionality at very high and low temperatures.
Parker’s VM125-75 has the chemical resistance, high temperature compression set resistance and low temperature flexibility to meet the increasing demands of the industry. Approved to qualified products list, VM125-75 meets AMS7287, as well as the preceeding document, AMS-R-83485.
