About Washers

Electrical-Insulating Sleeve Washers
Also known as shoulder or insulator washers, these nonmetal washers block electrical current and prevent galvanic corrosion from mating different types of metal.
Nylon 6/6 washers have good abrasion resistance. Exposure to moisture may cause them to expand.
PTFE washers have excellent chemical resistance and a slippery surface that resists wear in high-friction applications.
Ceramic washers withstand high temperatures and resist moisture as well as hydrochloric and nitric acid gases.
Hard fiber washers resist organic solvents and petroleum-based oil.
