These products have been used in contact with air and a wide variety of fuels, lubricants, specific hydraulic fluids (MIL-PRF- 5606, MIL-PRF-83282, MIL-PRF-87257), and a variety of gas turbine engine lubricants, including higher thermo-oxidative stability (HTS) lubricants, including those conforming to MIL-PRF-23699 class HTS, MIL-PRF-7808 grade 4 and AS5780 class HPC, however usage is not limited to such applications. This material type has a typical service temperature range of -22 to +400 °F (-30 to +204 °C). These products are not suitable for use in phosphate ester based hydraulic fluids. Each application should be considered individually.
This standard establishes the dimensional and visual quality requirements, lot requirements and packaging and labeling requirements for O-rings molded from AMS7287 rubber. It replaces AMS-R-83485/1 and maintains the part numbering system, M83485/1-XXX, established in MIL-R-83485/1 and continued in AMS-R-83485/1. It shall be used for procurement purposes.
