FEATURES

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*
