About Washers

Metal-Bonded Sealing Washers
Create a stronger seal than metal or rubber alone. These one-piece washers are metal for strength with a bonded rubber seal that creates a tight grip. Made of neoprene, the seal has good oil and abrasion resistance. Washers are reusable.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
Hot-dipped galvanized steel washers are corrosion resistant in wet environments.
Aluminum washers are lightweight and corrosion resistant in wet environments.
