Key benefits Effective oil sealing: copper material deforms under torque to create a tight, leak seal between drain plugs, fittings, and oil pans. Corrosion resistant: copper withstands exposure to automotive oils and lubricants to maintain seal integrity over time. Easy to install: simple washer shape and consistent dimensions help ensure proper seating and sealing when assembling or reassembling components. Costeffective: pack of 10 washers provides replacement value for maintenance and repairs.
