STRESS SAVER® GYLON® Style 3505 NSF 61

STRESS SAVER® GYLON® Style 3505 NSF 61

NSF 61 Approved Gaskets » STRESS SAVER® GYLON® Style 3505 NSF 61

100% GYLON® PTFE with aluminosilicate microspheres GYLON® STRESS SAVER® Style 3505 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 Style 3505 GYLON® STRESS SAVER® the ultimate sealing solution for NSF 61 Drinking Water Systems.

FEATURES

 

  • Style 3505 GYLON® Stress Saver® is able to meet the stringent requirements of NSF-61 for potable water applications.
  • Versatility - Suitable for both metallic and non-metallic piping with either flat or raised face flanges
  • Chemical resistance – GYLON® 3505 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

 
BENEFITS

 

  • 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*
