The AUTOMAJOR 100-Pack Oil Drain Plug Crush Washer Assortment Kit is the ultimate collection of aluminum and copper crush washers for automotive professionals, DIY mechanics, and powersport enthusiasts. This comprehensive set includes 50 copper and 50 aluminum washers in 5 of the most commonly used sizes — covering virtually every vehicle on the road. Contents: 10 copper + 10 aluminum in each of the following sizes — 10mm / 0.39in, 12mm / 0.47in, 14mm / 0.55in, 16mm / 0.63in, and 18mm / 0.71in. Total 100 pieces organized by size for easy identification. The 10mm washers fit select Kawasaki, Ducati, and KTM motorcycles. The 12mm washers fit Toyota, Lexus, Scion, Nissan, and Infiniti vehicles (replaces Toyota 90430-12031 and Nissan 11026-JA00A). The 14mm washers fit Honda, Acura, Hyundai, Kia, Mazda, Chrysler, Dodge, Jeep, and most motorcycles (replaces Honda 94109-14000, Hyundai/Kia 21513-23001, Mazda 9956-41-400). The 16mm washers fit Subaru, BMW, MINI, Toyota 86, and Scion FR-S (replaces Subaru 803916010, BMW 07119963252). The 18mm washers fit BMW, Volvo, Dodge RAM, and select Toyota models (replaces BMW 07119919143, Volvo 9454877). Crush washers are single-use sealing components that should be replaced at every oil change. When torqued, the soft metal washer compresses and deforms to fill microscopic surface imperfections between the drain plug and the oil pan, creating a tight, leak-free barrier. Reusing an old crush washer is one of the most common causes of oil drips after service — the washer has already been compressed and will not seal properly a second time. This assortment includes both copper and aluminum washers because different applications call for different materials. Aluminum washers are ideal for aluminum oil pans (same-metal contact eliminates galvanic corrosion). Copper washers are softer, more malleable, and create a tighter seal on cast iron and steel surfaces. Having both materials on hand means you always have the right washer for the job. With 100 washers in this kit, a professional shop can service dozens of different vehicles without needing to stock individual packs for each brand. A DIY mechanic with multiple vehicles never has to worry about running out or ordering the wrong size. Keep this assortment in your toolbox, garage, or service bay — ready for any oil change that comes your way. Backed by AUTOMAJOR — trusted replacement parts for automotive professionals and enthusiasts.
