    Sealing Washers

    Prevent leaks while distributing weight evenly under nuts and screws. These washers compress as you tighten to keep air and fluid in, and dust and contaminants out. Use them anywhere you need a tight seal, such as protecting electronics from moisture or keeping lubricants contained in machinery.

    Resist leaks better than metal sealing washers, but are more susceptible to wear and tear. Reuse these washers a handful of times, as long as the material isn't damaged.
    Cork/Neoprene—Combine the cushioning of cork with the durability of rubber. These washers dampen vibration and noise in rattling assemblies while maintaining a strong seal.
