    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.

    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.

    Install these washers under screw heads and nuts. When compressed, the PVC sealant squeezes into every crevice, creating an impervious 360° seal that stops liquids or gases from trickling along the length of the screw. These washers are not reusable.
    18-8 Stainless Steel and PVC—The PVC sealant resists acids, alcohols, solvents, and detergents. However, the metal is more likely to rust than 316 stainless steel.
    Chemical-Resistant 316 Stainless Steel and PVC—Every part of these washers resists acids, alcohols, solvents, and other aggressive substances. They are commonly used in harsh environments, such chemical processing plants.

    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

    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.
