The flat edges on these square-profile seals provide more sealing surface than round-profile seals. They’re made of 98% silica to resist temperatures up to 2300° F.

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

Alumina silicate is loosely woven to create these ceramic seals that are stronger and more flexible than Ultra High- and Low-Temperature Rope Seals. They can handle temperatures from –300° to 2300° F.

Able to withstand temperatures up to 1000° F, these seals have a fiberglass cover and core that resists most refrigerants, salts, and grease.

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. These seals resist steam, most refrigerants, salts, and grease. They can withstand temperatures up to 500° F.
