    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.

    Also known as crush washers, these are made of soft metal that deforms under pressure to fill gaps around the nut or screw. Often found in oil drain valves, they withstand stress and wear better than plastic and rubber washers, but aren't as leak-resistant. Metal sealing washers are not reusable.
    Copper—Softer than aluminum washers, these deform easily to create a tight seal with less effort. They resist rusting in corrosive environments, but will develop a green patina over time.

    Create space to clean between components on food processing lines and other sanitary equipment. A smooth finish and rounded edges eliminate pits or crevices where bacteria can collect. Made of stainless steel, these spacers withstand frequent washdowns with harsh cleaners and sanitizers. They have a seal that blocks water and contaminants from entering the body. All are FDA compliant for safe contact with food.
    304 Stainless Steel—Won't corrode from frequent washdowns and stand up to most cleaners and detergents.
    Buna-N Seal—With the best oil resistance, this seal won’t swell or soften when it touches oil, grease, or fuel. However, it will break down if exposed to synthetic lubricants.
