GYLON EPIX™ Style 3500 Gaskets - PTFE with Silica Filler

PTFE Gasketing with Silica Filler for Aggressive Media

GYLON EPIX™ Style 3500 is a high performance, silica filled PTFE gasket sheet material designed for use with strong acids, solvents, hydrocarbons, and other aggressive media. GYLON EPIX™ Style 3500 withstands a wide range of chemicals for extended service in a wide variety of applications.

GYLON EPIX™ will provide superior functional performance by combining the traditional attributes of GYLON® with an innovative surface design. It offers a broader range of applications than traditional PTFE gaskets used in worn and pitted flanges. In addition, GYLON EPIX™ delivers the tight sealing and load retention properties of 1/16” (1.6mm) and the conformability of 1/8” (3.2mm). The hexagonal profile provides improved compressibility and recovery. The profiled surface reduces the contact area during initial compression to concentrate the compressive force of the flange for improved sealability.
  • One thickness does the job of two
  • Seal performance and load retention equal of 1/16” (1.6mm)
  • Compressibility and forgiveness/conformability of 1/8” (3.2mm)
  • Patented hex profile creates superb sealing and ability to conform to imperfect flange surfaces
  • Same material as traditional GYLON®
