THREADED CONNECTIONS SEALING LUBRICANT Russian patent published in 2017 - IPC C10M145/10 C10M147/00 C10M125/02 C10N40/34 F16L15/00

Abstract RU 2607520 C1

FIELD: machine building.

SUBSTANCE: present invention relates to lubricant for sealing of threaded connections, containing fluorine-containing copolymer, graphite, corrosion inhibitor, supplemented with resilient elastic acrylic copolymer and solvent at following ratio of components in %: Resilient elastic acrylic copolymer 10–18; Fluorine-containing copolymer 25–40; Graphite 4–6; Corrosion inhibitor 0.5–5.0; Solvent 49–58.

EFFECT: technical result of this invention is improvement of threaded connections sealing lubricant reliability and efficiency due to reducing force during multiple screwing down - unscrewing and preventing metal “baking”.
