High-Temperature Rope Edge Seals

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 to resist temperatures up to 2300° F.

Round-Profile Ultra
High-Temperature Rope Edge Seals

Made of 96% silica, these seals resist temperatures up to 1800° F.

High-Temperature Rope Edge Seals

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

High-Temperature
Ultra-Conformable Rope Edge Seals

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

Ultra High-Temperature Chemical-Resistant
Flange-Mount Rope Edge Seals

A ceramic cover makes these seals more chemical resistant than the seals with a silica cover. They resist acids (except hydrofluoric and phosphoric), diluted alkalies, most refrigerants, salts, and grease. Seals can withstand temperatures up to 1700° F.

High-Temperature Chemical-Resistant
Flange-Mount Rope Edge Seals

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.

Packing Seals

High-Speed Chemical-Resistant Packing Seals

Built for high-speed pump and valve applications, these super-tough seals are made of expanded-graphite yarn with carbon-yarn corners.

Abrasion- and Chemical-Resistant Packing Seals

Aramid and PTFE fibers are blended for seals that resist chemicals and abrasion. Use these seals in pumps.

Heat-Shielding Chemical-Resistant Packing Seals

Also known as 100% GFO, these expanded PTFE seals contain graphite powder, which dissipates heat away from the shaft and allows pumps to run cool at high speeds.

Chemical-Resistant Packing Seals

These lubricated PTFE fiber seals stand up to most chemicals. Use them in pumps and valves.

Hard Chemical-Resistant Packing Seals

These seals are made of PTFE fiber without a lubricant, so they’re harder than other chemical-resistant packing seals to handle high-pressure valve applications.

Packing Seal Tape

For use in valves and pumps, this thin, flexible tape is made from high-purity graphite with no fibers or binders that could contaminate your process line.
