Ensure a perfect hydraulic seal for the fluid and fuel systems of your agricultural machinery with our selection of copper washers. In this section, you will find copper sealing rings and gaskets in a wide variety of thicknesses and diameters (both metric and imperial), essential for sealing fittings, oil drain plugs, injectors, and high-pressure lines. Thanks to the natural malleability of copper, these washers deform plastically during mechanical tightening, filling micro-imperfections between the mating metal surfaces and eliminating the risk of fluid or gas leaks. Their excellent resistance to high temperatures, pressure, and the corrosive action of fuels and lubricants makes them indispensable for professional engine maintenance and hydraulic linkage overhauls on tractors and farm equipment.
