Electrical enclosures and electronics need washers that insulate, seal out moisture and absorb vibration. We stock rubber washers suited to electrical and electronic assemblies in every OD, ID and thickness.
Best materials for electrical use
We recommend Neoprene, Silicone and Fiber. Neoprene seals enclosures against moisture, Silicone tolerates heat near components and provides good insulation, and Fiber works well as a rigid insulating washer for conduit and terminal hardware.
Common sizes
- 1/4" to 1" OD for conduit knockouts
- 1/2" to 2" OD for enclosure seals
Key properties to look for
- Electrical insulation
- Moisture sealing
- Vibration dampening
