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.

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.
