Low Stress to Seal
Technical Data
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.
Material:
Designed for low stress-to-seal
services such as FRP and glass-lined
flanges, GORE-TEX® TriGuard ®
gaskets are ideal for high purity
applications and highly aggressive
fluids, including chlorine and
monomers. GORE-TEX® TriGuard®
gaskets combine all the properties of
expanded PTFE while providing
reliable sealing of the most
fragile flanges.
®
Look to GORE-TEX TriGuard
gaskets for superior performance in
three important 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® gasketing when you
need the highest level of confidence.

GORE-TEX® TriGuard® gaskets have the lowest Y value of
any PTFE-based gasket. What is important to users is that
less torque on bolts means less chance of cracking fragile
flanges. With a lower Y value, GORE-TEX® TriGuard®
gaskets provide a tighter seal at lower bolt loads than other
ePTFE and PTFE gaskets.

Processors of aggressive chemicals must meet stringent
requirements for leakage. They need to be confident that
there is no start-up leakage. And they must maintain a tight
seal to assure safety performance and minimize production
loss. The bubble test, a commonly used measure of
sealability in the fluid sealing industry, shows that
GORE-TEX® TriGuard® gaskets seal at the low loads
required in fragile flange applications.
