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.
