FIELD: machine building.
SUBSTANCE: procedure for fabrication of sealing collar out of elastomer with filler non-uniformly distributed along cross section of collar consists in collar mould successive filling. First, a working edge is filled with mixture including 10-20 % of nano particles, further there is performed thermo-stating. The rest part of the mould is filled with mixture containing 10-20 % of filler with dimension of particles 150-200 mcm and thermo-stating is performed.
EFFECT: increased reliability of sealing.
