These loosely knitted fiberglass seals are more flexible, compressible, and conformable than High-Temperature Rope Seals. The looser construction also makes them more likely to absorb liquids. Push them into the groove that’s commonly built into oven doors, furnaces, and tanks. They resist bleach, solvents, and most acids (do not use with hydrofluoric acid, hot phosphoric acid, and wet hydrogen chloride).

Alumina silicate is loosely woven to create these ceramic fiber seals that are stronger, more flexible, and able to resist higher temperatures than Ultra-High- and Low-Temperature Rope Seals. They are commonly used as to tie products together during high-temperature processing, but they can handle cryogenic applications just as well. They won’t burn and they resist molten metal splash. These seals also resist steam, salts, grease, detergents, bleach, and hydraulic fluid; however, they will absorb these substances. Push them into the groove that’s commonly built into oven doors, furnaces, and tanks.
