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.

High-Temperature Flanged Rope Seals

In addition to high temperatures, these seals have a fiberglass fabric 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.

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.

High-Temperature Rope Seals

A tighter braid makes these fiberglass seals more durable than High-Temperature Ultra-Conformable Rope Seals. 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 bleach, solvents, and most acids (do not use with hydrofluoric acid, hot phosphoric acid, and wet hydrogen chloride).

High-Temperature Ultra-Conformable Rope Seals

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).
