Installation Guide: GORE® GR Sheet Gasketing
Installation Guides, United States
To achieve a reliable seal, adequate gasket stress must be applied during installation. The Gore torque tables provide end-users with an estimation of bolt preload for use during flange assembly.
1. Select the correct size gasket to match the flange dimensions.
Choose a gasket that matches the pressure class and nominal diameter of the standard flange:
2. Determine Torque Value
To achieve a reliable seal, adequate gasket stress must be applied during installation. The tables provide an estimation of torque for use during assembly of pipe flanges.

EN1514-1 Gaskets in EN 1092-1 Type 11 Form B
The German Chemical Industry Association, VCI, provides guidelines for bolted flange joint installation in chemical processing plants. These guidelines are based on a different set of inputs resulting in torque values different from those provided in the Gore EN1514-1 torque table. Gore has reviewed the August 2011 guidelines and supports the use of these VCI torque values when installing GORE® GR Sheet Gasketing.
3. Review and Follow Standard Bolted Flange Assembly Practices.
GORE® Gasketing Products do not require special assembly practices. However, utilizing industry best practices is always recommended when assembling a bolted flange joint. Such practices have been developed by ASME, European Sealing Association (ESA), the Fluid Sealing Association (FSA) and the Association of German Engineers (VDI).
