ТУ У 24.6-30802090-059:2007 Agrinol ZHT-79L is a plastic lubricant utilized for car breaking devices of rolling stocks for the following purposes:- for greasing rubber and rubber cloth sealing parts of car breaking devices;- in distribution and switching stopcocks;- for greasing attrition faces «metal - metal» and «metal - rubber» parts and units of break devices.The lubricant is also used for greasing attrition faces of electric equipment of rolling stocks:- in bearings of machines, joinings, all relays, windshield wipers, pressure regulators etc.;- in cylinders and sealing glands of rubber pistons of pneumatic drives of current receiver contractors and other electric devices, except cases when leather piston glands are used.The lubricant is efficient at the temperature from minus 60°С to 120°С. The lubricant is efficient at the temperature not higher than 150°С in a short-term period.Guarantee period of storage - 1 year from the day of manufacture.
