Applications & selection
Typical uses
- Flange face protection
- Corrosion prevention
Industries: Chemical.
Selecting the right construction
Specify flange dimensions, ring thickness, lining material and exposed medium. Confirm fit with adjacent gaskets and mating flanges.
Chemical resistance depends on the polymer, fillers, inserts and process conditions. Confirm the exact medium and concentration; general PTFE properties do not establish a complete assembly's service rating.
