Lincoln 40544 Piston Washer

• A piston washer is a small, usually flat, metal component that sits between the piston and the connecting rod, providing a surface for the piston to rotate smoothly. These washers contribute to reducing friction and wear in the engine. They are usually metal or plastic. They are also important for preventing galvanic corrosion, particularly by insulating steel screws from aluminium surfaces. They may also be use in rotating applications, as a bearing. These are commonly use to spread the load on thin sheet metal, and are named after their use on automobile fenders.
