Electrical-Insulating Sleeve Washer

Manufacturer part: 93835A370

Cover screw threads to stop electrical current in its tracks and prevent short circuits. These washers create a barrier between the screw threads and the mating surface when mounted in through holes. This barrier also extends the life of your assembly by preventing galvanic corrosion, which is when two different metals rust more quickly due to contact with each other.Flat Edge—The flat edge distributes weight evenly to take pressure off screw heads.PTFE—These washers insulate better than nylon and withstand higher temperatures, so they're a great choice for high-voltage equipment, such as capacitators, transformers, and semiconductors. They resist harsh acids, bases, solvents, and corrosive cleaners.
