Abrasion-Resistant Rubber and Plastic Sealing Washers
Made of durable material, these washers resist wear from rubbing and scraping surfaces. They create a light duty seal around fasteners to prevent fluids from leaking and damp vibration.
ePTFE plastic washers have excellent weather resistance.

Angle Bumpers
These bumpers are at a 90° angle to protect corners on equipment, walls, and docks from damage caused by carts, vehicles, and other moving objects. All have a hard rating to withstand high levels of impact. They are nonmarring and can be used outdoors.
Unthreaded-hole bumpers mount with screws. Polyurethane foam bumpers resist abrasion better than plastic or vinyl plastic bumpers.
UV-resistant bumpers won’t dry out and become brittle when exposed to UV rays.

Adhesive-Back Bumpers
Press these bumpers into place with the adhesive backing. Use them as feet and spacers on instruments and small appliances to limit sliding, vibration, and noise. They're comparable to Bumpon bumpers.
Bumpers with a soft rating offer cushioning. Polyethylene foam bumpers cushion during impact and are nonmarking. They are not for use outdoors.
Silicone foam bumpers cushion during impact and withstand a wider range of temperatures than other bumpers. They are nonmarking and can be used outdoors.
