A wide temperature range makes these ceramic seals equally suitable for use in cryogenic applications as they are for extreme-heat applications. They’re made from tightly woven calcium alumina silicate, so they won’t burn and they resist molten metal splash. They 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.

Alumina silicate is loosely woven to create these ceramic seals that are stronger, more flexible, and able to resist higher temperatures than Ultra High- and Low-Temperature Rope Edge 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.

A ceramic cover makes these seals more chemical resistant than the seals with a silica cover. Seals resist acids (except hydrofluoric and phosphoric), diluted alkalies, most refrigerants, salts, and grease. The flange on these seals slides into a slot that is commonly found on oven, furnace, and boiler doors; it can be positioned to cover large gaps.

In addition to high temperatures, these seals have a fiberglass cover and core that resists most refrigerants, salts, and grease. They’re flexible and compressible, and are often used as caulking and for filling expansion joints. The flange on these seals slides into a slot that is commonly found on oven, furnace, and boiler doors; it can be positioned to cover large gaps.
