Plastic lubricant for auto-brake devices ZhT-79L is used in brakes of locomotives and cars. It does not cause rubber swelling, has good anti-wear characteristics, frost and water resistance. It is efficient at temperatures from –60 to 120 ° С.
ZhT-79L railway grease is made from a mixture of organosilicon liquid and isoparaffin oil, thickened with lithium stearate. Contains antioxidant and plasticizer.
Application area
- For lubrication of rubber and rubber-fabric sealing parts of brake devices;
- In distribution and switching plug valves;
- For lubrication of friction surfaces “metal - metal” and “metal - rubber” of parts and components of brake devices.
