Description

Working NGZh-5U liquid (TU 38.401-58-57-93) — the synthetic fire and explosion safe, erosion-resistant liquid made on the basis of air of phosphoric acid, containing a package of the additives improving viscous, anti-hydrolytic, anti-oxidizing, anticorrosive and anti-erosive properties. Has temperature of spontaneous ignition of 595-630 °C, slowly burns in a flame, does not sustain combustion and  does not extend a flame. NGZh-5U liquid is completely compatible to  NGZh-4 and NGZh-4U liquids. It is applied in hydraulic systems  of the planes SILT-86, SILT-96, TU-204  , etc. in    the range of temperatures from-60 to +150 °C with nominal pressure to 21 MPa.
