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