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.
Hard fiber washers resist organic solvents and petroleum-based oil.

Electrically Insulating Hard Fiber
- Color: Gray
- Max. Temperature: 235° F
- Tensile Strength: See Table
- Impact Strength: 2.5 ft.-lbs./in. (Good)
- Hardness: Rockwell R70 (Hard)
- For Use Outdoors: No
