Valves - diaphragms

PTFE diaphragms

Overview

PTFE diaphragms

Polytetrafluoroethylene (PTFE) offer the ultimate chemical resistance and purity. Our PTFE diaphragms are extremely chemically resistant, often used with heptane and methyl chloride.

All our diaphragms are laser-etched with cure dates and batch numbers, ensuring that they are completely traceable.

Features and benefits

  • Extremely chemically resistant
  • Good steam resistant
  • Only available for tank valves
  • Must be steamed prior to use
