STRESS SAVER® GYLON® Style 3504 Gasket Seals

100% GYLON® PTFE with aluminosilicate microspheres

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*

*Style 3505 GYLON^® Stress Saver^® is able to meet the stringent requirements of NSF-61 for potable water applications.
