Sealing Washers

Prevent leaks while distributing weight evenly under nuts and screws. These washers compress as you tighten to keep air and fluid in, and dust and contaminants out. Use them anywhere you need a tight seal, such as protecting electronics from moisture or keeping lubricants contained in machinery.

Metal

Also known as crush washers, these are made of soft metal that deforms under pressure to fill gaps around the nut or screw. Often found in oil drain valves, they withstand stress and wear better than plastic and rubber washers, but aren't as leak-resistant. Metal sealing washers are not reusable.

Copper—Softer than aluminum washers, these deform easily to create a tight seal with less effort. They resist rusting in corrosive environments, but will develop a green patina over time.

Cellulose-Filled Copper—The easiest washers to crush. These washers are embedded with cellulose, which makes them more flexible than other metal washers for a tighter seal. They resist rusting in corrosive environments, but will develop a green patina over time.

Aluminum—These washers are an economical alternative to copper. They have similar corrosion resistance but require more effort to crush.

Hard Fiber

An economical alternative to metal crush washers, these compress easily to create a seal with less effort. However, fiber washers degrade faster than metal washers and aren't as heat resistant. They also don't seal quite as tightly as their plastic or rubber counterparts. These washers are reusable, as long as the material isn't damaged.

Shims

With thickness tolerances as fine as a strand of hair, these shims precisely align, space, and level components on shafts, arbors, and machinery.

You can stack multiple shims to achieve your exact thickness, but stacking more than four may cause them to shift. Remember, fewer shims are better, so a couple of thicker shims are more stable than a bunch of thin shims.

Aluminum—These shims are an alternative to stainless steel for rust resistance but aren't as hard so they may not retain their shape as well. One-third the weight of steel, they’re commonly used in robotics and automation.

Brass—With a warm, polished look, these shims are often chosen for their appearance. Similar to 18-8 stainless steel, brass is corrosion resistant enough to stand up to wet environments.

Sealing Washer Assortments

Keep a collection of metal sealing washers on hand to prevent leaks while distributing weight evenly under nuts and screws. Also known as crush washers, these deform when tightened to lock air and fluid in, while keeping dust and contaminants out. They are not reusable.

Labels in the lid include our part numbers, so it's easy to replenish the assortments.

Copper—Softer than aluminum washers, these deform easily to create a tight seal with less effort. They resist rusting in corrosive environments, but will develop a green patina over time.

Aluminum—These washers are an economical alternative to copper. They have similar corrosion resistance but require more effort to crush.
