Heat-Dissipating Chemical-Resistant Packing Seals

The graphite filler in these expanded PTFE seals dissipates heat away from the shaft, so your pump runs cool at high speeds. Use these seals in applications involving acids, alkalies, brines, and solvents. Cut them to size with a knife; then pack them into place.
