Summary:PURPOSE: A composition for rubber packing of an engine oil filter is provided, to prevent the leakage of engine oil even under the operation at rigorous temperature by modifying the component of a rubber packing. CONSTITUTION: The composition comprises 100 parts by weight of a cold-resistant acryl-based rubber having a glass transition temperature of -42 to -40 deg.C; 60-80 parts by weight of HAF(high abrasion furnace) carbon black having a specific surface area of 81-100 m2/g; and 1.0-1.6 parts by weight of a carboxyl vulcanizing agent. Optionally the composition comprises further 30-50 parts by weight of low viscosity oil; 30-40 parts by weight of zinc oxide; 5-15 parts by weight of 2-hydro antiaging agent; and 1-8 parts by weight of tetramethyl thiuram dihydro(TMTD).
