Square-Profile Ultra-High-Temperature Rope Seals

The flat edges on these square-profile seals provide more sealing surface than round-profile seals. They’re made of 98% silica fiber 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.

Round-Profile Ultra-High-Temperature Rope Seals

Made of 96% silica fiber for excellent temperature resistance. These round-profile seals are 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-Temperature Flanged Rope Seals

These seals have a strong Inconel core covered with woven silica fabric that’s been treated to withstand extremely high heat. They resist 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.
