10PCS/Pack Copper Washer Solid Gasket Sump Oil Seal This pack consists of 10 solid copper washers sized 22 x 27 x 2 mm. They are crafted to provide a reliable seal for sump oil applications and related fittings. The copper construction helps form a tight crush gasket that adapts to irregular sealing surfaces, helping to minimize leaks. Key benefits Reliable oil sealing: Copper washers crush slightly to create a tight seal for oil sump connections. Corrosion and heat tolerance: Copper offers good resistance to oilbased fluids and temperatures commonly found in engine and hydraulic systems. Value pack: 10 pieces per pack ensures you have spares on hand for replacements or multiple applications. Easy to install: Simple washerbased sealing that fits standard 22 x 27 x 2 mm sizing.
