VNIINP-283 grease (TC 38.101281-89) - perfluoropolyether thickened with an inorganic thickener; contains metal oxide. Grease has good resistance to gaseous oxygen, water resistance, sealing properties. It is efficient within the temperature range from -45 to + 200°C.
It is used in friction units used in contact with gaseous oxygen at pressures up to 25 MPa, in threaded joints at an oxygen pressure inside the pipeline up to 100 MPa. Substitute - VNIINP-282 (from -150°C).
