The PTFE coating on these fiberglass seals is slippery, so they are easier than the other seals to press fit into oven, furnace, and boiler doors. The PTFE resists most acids, alkalies, refrigerants, salts, and grease. The flange is also handy for positioning over uneven gaps.

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.

A tighter braid makes these fiberglass seals more durable than High-Temperature Ultra-Conformable Rope Edge 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).

These loosely knitted fiberglass seals are more flexible, compressible, and conformable than High-Temperature Rope Edge 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).

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.
