About Washers
More
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.
Viton® fluoroelastomer and fluoroelastomer washers withstand oil, chemicals, and high temperatures better than neoprene washers.
Cork washers are made of a blend of cork granules and neoprene, so they are highly compressible and offer excellent cushioning and vibration damping.
FDA-compliant washers are safe for direct contact with food.
