FIELD: mechanical engineering; movable and fixed joints.
SUBSTANCE: proposed shaped sealing member is provided with body permeable and resilient reinforcing element whose porous space is filled with filler. Sealing element is covered from outside with multilayer coating impermeable for working medium and made up of layers of different sealing and reinforcing articles connected to each other to form solid part. Versions of making filler are described in invention.
EFFECT: improved stability of sealing member in aggressive media, provision of elastic liability at higher and lower operating temperatures.
