GYLON® Style 3545 Microcellular PTFE Gasketing for Low Bolt Load Applications

Microcellular PTFE Gasketing for Low Bolt Load Applications The GYLON® Style 3545 is a highly compressible microcellular PTFE with a rigid PTFE core for improved handlability. The GYLON® 3545 designed to compress and conform to irregular or damaged surfaces, making it suitable for flanges that generate lower compressive stresses, such and glass-lined flanges and equipment.



  • Tight seal
  • Highly compressible PTFE outer layers seal under low bolt load
  • Compressible layers conform to irregularities, especially on warped, pitted, or scratched flanges
  • Rigid PTFE core reduces cold flow and creep
  • Withstands a wide range of chemicals
  • Can be cut from larger sheets, reducing inventory costs and expensive downtime
  • Rigid PTFE core facilitates installation, especially on large diameter flanges and hard-to-reach areas
  • Will not support flame
  • Will not support bacterial growth
