    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.
    Metal
    Image of Product. Front orientation. Sealing Washers. Metal.
    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.

    Bonded Sealing Washers

    Image of Product. Front orientation. Sealing Washers. Bonded Sealing Washers.
    These washers create a stronger seal than metal or rubber alone to lock air and fluid in, while keeping dust and contaminants out. The flexible rubber layer compresses to fill gaps, while the metal backing stops the washer from squeezing through the hole. These washers are a great solution if you have a hole larger than your fastener that you need to seal. Reuse them a handful of times, as long as the material isn't damaged.

    18-8 Stainless Steel—The choice for wet and outdoor environments, these washers resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
    Black-Oxide 18-8 Stainless Steel—Typically chosen for their appearance, these washers have a dark, matte coating to create a finished look. They resist rust in wet and outdoor environments, but won't hold up to harsh chemicals as well as 316 stainless steel.
    Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these washers won't degrade when exposed to harsh weather, salt water, and most chemicals.
    High-Strength 17-7 PH Stainless Steel—Some of the strongest stainless steel washers we offer, these are comparable to high-strength Grade 8 steel. They won’t rust in wet and outdoor environments, but they can’t handle the harsh chemicals that 316 stainless steel can.

    Hard Fiber Washers

    Image of Product. Front orientation. Washers. Hard Fiber Washers.
    The least likely to scratch or mar delicate mounting surfaces, these washers are made of hardened cotton fiber. They are also naturally nonconductive, so they are a great choice for insulating nuts and screws to prevent unintended charges. However, fiber washers will break down faster than other washers and will need to be replaced more often.

    Plastic Washers

    Image of Product. Front orientation. Washers. Plastic Washers.
    All of these washers are lightweight, nonconductive, and naturally rust resistant. They are commonly used in electronics and automation applications to take the pressure off screws and nuts and protect mounting surfaces.
    Nylon—The most popular plastic washers, these are strong, durable, and economical. Nylon will swell and weaken when exposed to moisture, so these washers are best for dry environments.
    Moisture-Resistant Delrin® Acetal—The best plastic for damp and wet environments, these washers won't swell or lose their strength if exposed to moisture.
    Low-Friction Impact-Resistant UHMW Polyethylene—The slippery surface reduces friction between the washer, fastener, and mounting surface to prevent sticking when fastening and loosening. These washers also resist bumps and vibration without cracking or denting.
    Chemical-Resistant High-Temperature PTFE—The most chemical-resistant plastic washers we offer, these stand up to the widest range of harsh acids, bases, solvents, and corrosive cleaners, even at temperatures up to 500° F. Their slippery surface reduces friction between the washer, fastener, and mounting surface to prevent sticking when tightening and loosening. They are also good electrical insulators.
    High-Strength High-Temperature PEEK—These washers bear heavier loads than most other plastic washers. In addition, they won't melt or deform when exposed to high temperatures up to 550° F. PEEK washers aren't very impact resistant, however, so they may crack or dent if subjected to hard bumps and vibrations.
    Extreme-Strength High-Temperature Carbon-Filled PEEK—Second only to phenolic in terms of strength, these washers stand up to high-stress applications. They won't melt or deform when exposed to high temperatures up to 500° F.
    Extreme-Temperature Polyimide—Our most temperature-resilient plastic washers. These won't deform or lose strength at temperatures as low as -450° F and as high as 750° F to handle everything from liquid nitrogen to heating elements. They are also good electrical insulators.
