  • Overview

Features and Benefits:

  • Versatility - Suitable for both metallic and non-metallic piping with either flat or raised face flanges
  • Chemical resistance – GYLON® 3504 is ideal for a wide range of caustics and acids, helping to simplify the selection process
  • Limited Creep and Cold-Flow – Greatly reduces the leakage after installation and system cycling
  • Superior Physical Properties – Higher temperature and pressure capabilities as compared to rubber gaskets
  • Homogeneous Construction – Single piece design helps avoid permeation, delamination, fold-over of PTFE envelopes and potential splitting when installed against raised face flanges
  • High purity – FDA, USP Class VI, and NSF-61*
