Supplier: Garlock Sealing Technologies
Garlock Sealing Technologies has
expanded its line of low-load gaskets for sealing metallic and non-metallic
piping systems with the addition of its 3504 GYLON® STRESS SAVER gasket for
industrial applications such as chemical processing, semiconductor
production and pulp and paper. Also being added is the 3505 GYLON STRESS
SAVER for potable water applications.
The new gaskets are designed to seal lightweight metallic, plastic and
fiberglass flanges that cannot provide the proper loads required to compress
conventional fiber or PTFE gaskets. The molded, raised, concentric ribs
allow for a more concentrated gasket load, creating a tighter seal with less
torque on both flat and raised face flanges.
The gasket material - 100% GYLON PTFE with glass microspheres - provides
superior cold-flow and creep resistance, eliminating the need for frequent
retorquing. In ongoing laboratory testing under controlled conditions, a
3504 GYLON STRESS SAVER gasket installed in fiberglass flanges has
logged more than 3,000 thermal cycles without leaking or needing to be
The field-proven Blue GYLON material gives the gaskets better chemical
resistance and higher temperature (-450°F to +500°F) and pressure
capabilities than other low-load gaskets. In addition the one-piece
construction prevents leaching, delamination and foldover for easy
installation, removal, and more reliable service.
Style 3504 is in compliance with FDA and USP Class VI requirements, and
style 3505 undergoes special manufacturing and packaging requirements to
meet NSF-61 certification for potable water applications.
