Heat-Shielding 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.
GFO seals, also known as 100% GFO, are made entirely of Gore materials.
