Outstanding chemical resistance at elevated temperatures

Blind Flange

  • Virtually inert to most organics, acids and bases
  • Usable up to 260°C / 500°F but weakens significantly
  • Excellent electrical insulator
  • High purity for sensitive pharmaceutical and food type applications

PTFE flanges are made from the fluoropolymer polytetrafluoroethylene and are known for being exceptionally corrosion resistant 

PTFE Threaded Flange

and inert at elevated temperatures. PTFE flanges are inert to most chemical environments including organics, acids, bases, mixed chemicals and 

hyrdofluoric acid. Additionally PTFE flanges are bio-inert and will not leach into or contaminate sensitive 

pharmaceuticals or food based products.

Compared to other high performance polymer flanges like PEEK or PVDF, PTFE flanges offer the best all-around corrosion resistance especially at elevated temperatures. However the trade-off for its extraordinary corrosion resistance is the lower tensile strength compared to PVDF or PEEK flanges.
