FIELD: construction.
SUBSTANCE: for prevention and elimination of gas leaks via stop valves leak passages at the range of working environment temperatures from minus 45°C to plus 160°C and higher, and also for corrosion prevention in metal parts of sealing units that operate in above mentioned ranges of temperatures, paste contains the following components in wt %: graphite colloid preparation 1.5-9.0, polytetrafluoroethylene 5-14, multifunctional additive 2.5-7.0, mineral oil thickned with lithium-zinc soaps of synthetic fatty acids up to 100. Multifunctional additive contains 1.4-di(N-arylsulfonylamino)-2(thiobezthiasol)benzol.
EFFECT: increased efficiency of stop valves operation due to leaks reduction via its stop unit.
