High-Temperature Mica Washer

Manufacturer part: 91619A500

These washers won't melt, stick, or become brittle, even when exposed to temperatures as high as 1050° F. They make excellent insulators and are often used to secure electrical connections in transformers. Mica can chip and flake due to wear, however, so these washers are not recommended for high-vibration applications.
