Garlock Expands Line of Low-load Gaskets
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 retorqued.
