    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 and Neoprene—Withstand prolonged exposure to wet and outdoor environments without rusting.
    Galvanized Steel and Neoprene—Combine the strength of steel with the rust resistance of stainless steel. These washers are an economical alternative to 18-8 stainless steel in wet and outdoor environments. However, they typically have a shorter lifespan since the galvanized coating wears off over time.
    Aluminum and Neoprene—These washers are as corrosion resistant as stainless steel but not as strong.

    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.
    Neoprene—If you're not sure which material best suits your needs, these versatile washers are a great solution. They offer a good balance of strength and flexibility to hold a tight seal, even in wet and outdoor conditions. These washers also withstand salt water and mild chemicals, such as detergents. However, they don't resist oil, grease, or fuel as well as Buna-N washers.
    Oil-Resistant Buna-N—With the best oil resistance of all our rubber washers, these won't swell or soften when they touch oil, grease, or fuel. However, they will break down if exposed to synthetic lubricants.
    Oil-Resistant Aramid-Reinforced Buna-N—These washers are embedded with aramid, which is the same material used in bulletproof vests. This addition makes them stronger and more heat resistant than standard Buna-N washers for a longer lifespan. They won't degrade when exposed to oil, grease, and fuel.
    Weather-Resistant EPDM—The best choice for outdoor use, these washers withstand long-term exposure to sunlight, rain, and ozone. However, they can't handle oil, grease, or fuel like Buna-N washers can.
    Weather- and Chemical-Resistant Santoprene—Not only will these washers withstand sunlight, rain, and ozone, they also won't degrade when exposed to acids and other harsh chemicals. They are more wear resistant than EPDM washers to stand up to repeated use.
    Chemical-Resistant Fluoroelastomer—The best chemical resistance of all our rubber washers. These withstand oil, grease, fuel, solvents, synthetic lubricants, and acids, even at high temperatures. They are also stiffer than other rubber washers, so they are better at distributing weight.
    High-Temperature Silicone—Withstand the widest temperature range of all our rubber washers. They resist detergents but will break down when exposed to oil, grease, and fuel.
    High-Temperature Chemical-Resistant Fluorosilicone—These washers handle a similar temperature range as silicone and are nearly as chemical resistant as fluoroelastomer. Commonly used in the aerospace industry, they withstand oil, grease, and fuel.
    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.

    Extreme heat and cold pose no problem for these resilient sealing washers. They won't deform or lose strength at temperatures as low as -400° F and as high as 525° F to handle everything from liquid nitrogen to heating elements. They are also the most chemical-resistant plastic washers we offer to withstand a wide range of acids, bases, solvents, and corrosive cleaners. ePTFE is more flexible than standard PTFE, so these washers compress easily to hold a strong seal. Reuse them a handful of times, as long as the material isn't damaged.

    An economical alternative to metal crush washers, these compress easily to create a seal with less effort. However, fiber washers degrade faster than metal washers and aren't as heat resistant. They also don't seal quite as tightly as their plastic or rubber counterparts. These washers are reusable, as long as the material isn't damaged.

    High-Pressure Bonded Sealing Washers

    Tested to hold up to high pressures, these washers create the strongest seal of all to lock in air and fluid and keep equipment running efficiently. They are often used on flanged connections to prevent leaks in pumps, hydraulic systems, compressors, and other pressurized lines. The flexible rubber or plastic layer compresses to fills gaps, while the metal backing stops the washer from squeezing through the hole.

    Fit under screw heads to stop leaks. These washers seal best on screws that aren't threaded all the way up to the head. Reuse them a handful of times, as long as the material isn't damaged.
    Oil-Resistant Zinc-Plated Steel and Buna-N—These washers won't swell or soften when they touch oil, grease, and fuel. However, they will degrade if exposed to synthetic lubricants. They are also are more susceptible to rusting than 18-8 and 316 stainless steel.
    Chemical-Resistant 18-8 Stainless Steel and Fluoroelastomer—These washers resist corrosion better than zinc-plated steel, so they're less likely to rust in wet and outdoor environments. The seal withstands high temperatures and won't degrade when exposed to acids, alcohols, solvents, synthetic lubricants, and harsh detergents.

    Commonly used under nuts, these washers wedge into threads to prevent liquids or gases from trickling along the length of the screw. Reuse them a handful of times, as long as the material isn't damaged.
    Oil-Resistant Zinc-Plated Steel and Buna-N—These washers won't swell or soften when they touch oil, grease, and fuel. However, they will degrade if exposed to synthetic lubricants. They are also are more susceptible to rusting than 18-8 and 316 stainless steel.

    Washdown Bonded Sealing Washers

    Image of Product. Bottom orientation. Sealing Washers. Washdown Bonded Sealing Washers.
    Maintain the washdown rating of your enclosure, even after drilling holes in it. These washers protect against high-volume jets of water, as well as dirt, ice, oil, and coolant. The flexible rubber layer compresses to fill gaps, while the metal backing stops the washer from squeezing through the hole. Reuse these washers a handful of times, as long as the material isn't damaged.
    18-8 Stainless Steel and EPDM—The best choice for outdoor environments, these washers withstand long-term exposure to sunlight, rain, and ozone.
    High-Temperature 18-8 Stainless Steel and Silicone—These washers resist freezing and scorching temperatures without deforming or losing strength.

    Sanitary Bonded Sealing Washers

    Image of Product. Front orientation. Sealing Washers. Sanitary Bonded Sealing Washers.
    Eliminate nooks and crannies under the nut or screw head where dirt and bacteria could collect. Unlike other bonded washers, the metal ring nests inside the rubber layer, creating a smooth outer surface that's easy to clean. These washers stand up to harsh cleaners and detergents and won't corrode from frequent washdowns. They're commonly found on equipment in food and pharmaceutical processing plants to prevent leaks and block out contaminants. Reuse them a handful of times, as long as the material isn't damaged.
    316 Stainless Steel and EPDM—These washers are highly resistant to tearing, scuffs, and scrapes. They are more economical than Fluoroprene Fluoroelastomer, however, they aren't as heat resistant.
    Chemical-Resistant 316 Stainless Steel and Fluoroprene Fluoroelastomer—These washers withstand higher temperatures than EPDM, so you can sterilize them with steam. They also resist more chemicals, such as oil, solvents, and acids.
