Description
Features & Benefits
- Tight seal
- Highly compressible PTFE seals under low bolt load
- Compressible material conforms to surface irregularities, especially on warped, pitted, or scratched flanges
- Reduced cold flow and creep
- Pure PTFE withstands a wide range of chemicals
- Soft PTFE can be cut easily from larger sheets, reducing inventory costs and expensive downtime
- Will not support flame
- Will not support bacterial growth
