About Washers

Able to withstand pressure greater than 7,000 psi, these one-piece bonded washers create the tightest seals. They are zinc-plated steel for corrosion resistance in wet environments. The Buna-N rubber seal has excellent abrasion resistance and good oil, weather, and chemical resistance. Washers are reusable.

Pressure-Rated Metal-Bonded Sealing Washers

These washers are rated to withstand pressure up to 100 psi. They are one-piece rubber-to-metal bonded washers that create a stronger seal than metal or rubber alone. Made of 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic. The silicone seal has excellent weather resistance. Washers are reusable.

Oil-Resistant Rubber Sealing Washers

These washers surpass other rubber washers when it comes to withstanding oil, grease, and fuel. They create a light duty seal around fasteners to prevent fluids from leaking and damp vibration.

Neoprene washers have good abrasion resistance.

FDA-compliant washers are safe for direct contact with food.

Metal Sealing Washers

Also known as crush washers, these compress when tightened to form a tighter, more durable seal than rubber washers. They are commonly used to seal fluids such as oil and fuel. Washers are not reusable.

Copper washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

Aluminum washers are lightweight and corrosion resistant in wet environments.

Extra-Tall Electrical-Insulating Rolled-Collar Sleeve Washers

The extra-tall sleeve extends into holes to provide more protection than other rolled-collar washers. As you tighten your screw, the rolled collar compresses under the head to create an insulating barrier between a screw shank and a mating surface. These nylon washers block electrical current and prevent galvanic corrosion from mating different types of metal. Exposure to moisture may cause them to expand.
