STRESS SAVER® GYLON® Style 3504 Full Face Gasket, PTFE with Aluminosilicate Microspheres, 0.125 Inch Thick, 4 Bolt Holes, For 3 Inch Pipe Flanges of Following Standard(s): ASME B16.5 Class 150; FDA Compliant

Garlock Part: 37035-5103

STRESS SAVER® GYLON® Style 3504 combines the proven sealing advantages of molded, raised ribs with the performance characteristics of the industry recognized GYLON® 3504 PTFE gasketing material. The combination of these two time-tested configurations make STRESS SAVER® GYLON® Style 3504 the ultimate sealing solution.

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*
