Rotary shaft PTFE radial lip seal
Dynalip® series
Saint-Gobain Performance Plastics
Saint-Gobain High Performance Seals has a complete line of polymer-based Dynalip® seals with many PTFE and PTFE blended sealing elements. These seals were designed to bridge the gap between conventional elastomer lip seals and mechanical face seals. Dynalip® seals can endure hostile environments, unlike elastomer lip seals, but similar to mechanical face seals. In addition, Dynalip® seals can be manufactured at a much lower cost than mechanical face seals.
