Pump Diaphragms & Garlock ONE UP® » GYLON® Style 3522 Diaphragm Material

100% PTFE diaphragm offering the longest service life in the industry. Exclusive to Garlock, the GYLON® PTFE Diaphragm material is made using a proprietary process that optimizes quality and uniformity. Using the best available technology, this material offers the longest service life in the industry and continues to outperform all competitive materials. GYLON® PTFE diaphragms offer the highest performance, lowest permeability, lowest creep, and longest flex life available and can be used in all diaphragm pump types.



  • Chemical and temperature resistant -
  • withstands aggressive chemicals and temperatures up to +500°F / +260°C.
  • Flexibility - up to four times the flex life of conventional PTFE
  • Reduced Void Content - results in less permeation, increased life,
  • reduced potential for cross-contamination of process media



  • Cost savings - longer diaphragm life means increased process uptime and decreased labor costs
