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. Use them in applications involving acids, alkalies, brines, and solvents. Cut these seals to size with a knife; then pack them into place.

Low-Friction Oil- and Water-Resistant Packing Seals

These seals require lighter packing pressure than standard oil- and water-resistant packing seals, so they cause less friction and reduce shaft wear. They’re made of graphite-impregnated aramid fiber and are for use in pumps and valves. Cut these seals to size with a knife; then pack them into place.

Packing Seal Tape

Plain Back

Adhesive Back

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. Graphite is self-lubricating, plus it provides outstanding performance over a wide temperature range.

Adhesive-back tape stays in place during installation.
