About Washers

High-Pressure-Rated Metal-Bonded Sealing Washers
Able to withstand pressure greater than 3,000 psi, these one-piece bonded washers create the tightest seals.
Use washers with a rubber seal under partially threaded screws or bolts that have a smooth shaft under the head. They are reusable. Washers with a Buna-N rubber seal have excellent abrasion resistance and good oil, weather, and chemical resistance. Washers with a Fluorocarbon rubber seal resist chemicals and withstand high temperatures.
Washers with PVC sealant create an impervious 360° seal around your fastener’s threads when tightened. They are not reusable.
Zinc-plated steel washers are corrosion resistant in wet environments. 304 stainless steel washers are more corrosion resistant than zinc-plated steel washers. They also have good chemical resistance. 316 stainless steel washers have excellent resistance to chemicals and salt water and may be mildly magnetic.

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.

Pressure-Rated Metal-Bonded Sealing Washers for Nuts and Washers
Also known as thread-sealing washers, use these under nuts and other washers. Rated to withstand pressure at or greater than 2,000 psi, these one-piece metal-to-rubber bonded washers create a stronger seal than metal or rubber alone. 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.

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.

Sanitary Metal-Bonded Sealing Washers
Eliminate cavities under screw heads where contamination may occur.
Washers with an EPDM seal are FDA compliant, 3-A certified, and meet NSF/ANSI standards for food processing. However, they don’t handle high temperatures as well as washers with a Fluoroprene fluoroelastomer seal.
Washers with a Fluoroprene fluoroelastomer seal have excellent chemical resistance and withstand high temperatures, so you can use them in steam sterilization. They are FDA compliant but are not 3-A certified and don’t meet NSF/ANSI standards.
