GORE® GR Sheet Gasket
The GORE® GR Sheet Gasket is designed to outperform traditional PTFE gaskets (including filled PTFE and virgin Teflon) and other ePTFE gaskets in applications involving steel piping and industrial equipment.
This product combines the chemical resistance of conventional PTFE with the added benefit of minimizing the relaxation and cold flow typically associated with that material. Additionally, it offers greater strength and dimensional stability compared to other ePTFE gaskets. Its ability to conform to rough or irregular sealing surfaces enables the creation of a firm gasket that ensures a tight and durable seal.
The GORE® GR Sheet Gasket is a versatile solution, suitable for both standard and custom shapes and sizes.
Key Features of the GORE® GR Sheet Gasket
Patented Manufacturing Technology
Made from 100% expanded ePTFE with advanced engineering, this gasket utilizes patented technology to achieve the highest level of expansion available in this type of material. Unlike other ePTFE products, which may contain unexpanded nodules, the GORE® GR Sheet Gasket delivers superior tensile strength and exceptional dimensional stability, making it ideal for demanding applications.
Exceptional Resistance to Relaxation and Cold Flow
Thanks to its high tensile strength, this gasket maintains dimensional stability in both thickness and width, surpassing other PTFE-based gaskets, including ePTFE ones. Its stable thickness allows it to retain a higher percentage of bolt load during use, ensuring reliable sealing even during thermal cycles and under high-temperature conditions.
The gasket’s width remains consistent without deformation, preventing intrusion into the pipe’s internal diameter and ensuring optimal process performance. Moreover, its dimensional stability reduces maintenance costs by minimizing the need for frequent retightening and replacement.
Superior Sealing Reliability
Crush resistance tests confirm that the GORE® GR Sheet Gasket withstands extreme conditions in industrial flange applications, providing a greater safety margin for reliable performance during installation and operation at elevated temperatures.
Chemically inert, this gasket is compatible with processes involving alkalis, strong acids, and solvents, resisting all substances within the pH range of 0-14, except molten alkali metals or elemental fluorine.
Enhanced Consistency and Performance
Gore’s precise manufacturing ensures uniform mass distribution, resulting in a more consistent and reliable seal. Unlike filled or skived PTFE gaskets, the GORE® GR Sheet Gasket quickly conforms to flange imperfections, eliminating the need for additional adjustments and ensuring a secure and efficient initial seal. This simplifies startup operations and expands its range of applications.
