description Gore Joint Sealant Overview
The Gore Joint Sealant is a form-in-place gasketing tape produced by W. L. Gore and Associates. Made from expanded polytetrafluoroethylene (ePTFE), the material is designed to be highly conformable, allowing it to effectively seal complex, irregular, or fragile industrial flanges.
The tape is used across various industries, including chemical processing and power generation, due to its chemical inertness and ability to withstand extreme temperatures. It is typically supplied in rolls that can be cut to specific lengths for custom applications.
help Gore Joint Sealant FAQ
What material is Gore Joint Sealant made from?
Gore Joint Sealant is made from expanded polytetrafluoroethylene (ePTFE), the same base polymer technology used in Gore-Tex fabrics. The expansion process creates a highly conformable microstructure that allows the tape to compress into irregular flange surfaces and fill gaps.
Who manufactures Gore Joint Sealant?
The product is manufactured by W. L. Gore and Associates, a company headquartered in Newark, Delaware. While best known to consumers for Gore-Tex waterproof fabrics, Gore is also a major global supplier of industrial sealing, filtration, and medical products.
What types of industrial flanges is Gore Joint Sealant used on?
The sealant is used on steel pipe flanges, glass-lined steel equipment, FRP (fiberglass reinforced plastic) flanges, and other irregular or fragile sealing surfaces where rigid gaskets may not conform adequately. It is particularly valued in chemical processing, pharmaceutical, and food and beverage industries where chemical resistance and reliable sealing are critical.
How is Gore Joint Sealant applied during installation?
The tape is applied directly onto the flange surface by hand, pressing it into place and overlapping the ends slightly to form a continuous ring. When the flange bolts are tightened, the ePTFE material compresses to fill surface irregularities while maintaining its chemical resistance and sealing integrity across a wide temperature range.
