PURPOSE: An o-ring rubber composition is provided to stick phenomenon, and to increase lubricant to prevent a stick phenomenon, thereby being capable of improving ride comfort. CONSTITUTION: An O-ring rubber composition for mono-tube type shock absorber seals between an oil chamber(5) and a gas chamber(4) by being inserted between a separation piston(6) and a tube(1). The rubber composition comprises: a polymer consisting of a nitrile rubber; 30-70 parts by weight of a talc-based titanium-based and silica-based inorganic filler based on 100.0 parts by weight of the polymer; 30-70 parts by weight of an organic filler comprising a carbon black with a diameter of 20-30 nm based on 100.0 parts by weight of the polymer. |
