Specification of Joint Sealants Gore-Tex
Low Stress to Seal GORE-TEX ® TriGuard ™ gaskets are used to seal fragile pipe flanges with low bolt load. Unlike other gaskets, they seal tight and stay tight, even with varying flange conditions. Designed for low stress-to-seal flanges, GORE-TEX ® TriGuard ™ gaskets are ideal for contamination services and highly permeable fluids, chlorine and monomer services. Unaffected by even the most aggressive chemicals, GORE-TEX ® TriGuard ™ gaskets com- bine all the properties of expanded PTFE with very good sealability. Look to GORE-TEX ® TriGuard ™ gaskets for superior performance in three im- portant areas: conforming to irregular surfaces, helping to protect flanges, and seal reliability. With over 25 years of manufacturing and technical experience, depend on GORE-TEX ® gasket when you need the highest level of confidence.
