Square-Profile Ultra High-Temperature Rope Edge Seals

The flat edges on these square-profile seals provide more sealing surface than round-profile seals. They’re made of 98% silica for excellent temperature resistance. They’re flexible and will conform to uneven surfaces. Push them into the groove that’s commonly built into oven doors, furnaces, and tanks. They resist water, salts, and diluted acids.

Ultra High- and Low-Temperature Rope Edge Seals

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.

Ultra High- and Low-Temperature Ultra-Conformable Rope Edge Seals

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.
