Used primarily as an insulator and spacer between two pieces of glass tapered joints. Takes high temperatures and will not stick to the glass. Ribbed for added flexibility.
Applications:
- Thread sealant tape or form-in-place large diameter gaskets
- Threaded joints
- Form-in-place gaskets
- Large diameter flanges
