GORE® Gasket Tape Series 1000 addresses all the challenges of reliably sealing large glass-lined-steel flanges.

A simple switch to high-performance, long-life GORE® GFO® Packing Fiber can help plant and mill pumps to operate more efficiently, and enable significant savings in power, water and maintenance costs.

Equipment made of glass-lined steel is used when manufacturing or processing aggressive chemicals such as aniline derivatives and strong acids such as sulfuric, nitric or hydrochloric acid. The Achilles heel of such glass-lined systems is the gaskets needed to seal the joints between components. Exposure to aggressive media causes the seals to degrade over time, resulting in damage to equipment and posing a health risk to operators. Replacing the seals costs a great deal of time and effort, with a corresponding drop in production output.

Visual step by step instructions for proper bolted flange assembly.

GORE Joint Sealant is ideally suited for large or complex steel flanges and equipment to achieve an incredibly tight seal. Available on a spool, the user can easily and quickly form a gasket in place on the flange, and achieve significant savings in material, labor, and lead-time over traditional large cut gaskets. Please follow the installation instructions in this guideline.
