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-Temperature Flange-Mount Rope Edge Seals

These seals have a strong Inconel core covered with woven silica yarn 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.
