A gasket rubber product made of a cured material of a fluorosilicone rubber composition containing: 100 parts by weight of an organopolysiloxane expressed by the following average composition formula: <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUP>1</SUP><SUB>a</SUB>R<SUP>2</SUP><SUB>b</SUB>R<SUP>3</SUP><SUB>c</SUB>SiO<SUB>(4-a-b-c)/2 </SUB><?in-line-formulae description="In-line Formulae" end="tail"?> wherein R<SUP>1 </SUP>indicates a trifluoropropyl group, R<SUP>2 </SUP>indicates a non-substituted or substituted monovalent aliphatic unsaturated hydrocarbon group having 2 to 8 carbon atoms, R<SUP>3 </SUP>indicates a non-substituted monovalent aliphatic saturated hydrocarbon group or aromatic hydrocarbon group having 1 to 8 carbon atoms, provided that a, b and c are positive numbers satisfying 0.96<=a<=1.01, 0.002<=b<=0.02, 0.96<=c<=1.06 and 1.98<=a+b+c<=2.02; 5 to 100 parts by weight of a silica-based filler; and a catalyst quantity of a curing catalyst.
