Seals made of polytetrafluoroethylene (PTFE) are indispensable in medical technology due to their unique properties. They enable secure and durable sealing that meets the high requirements for hygiene, sterility, and durability.

PTFE is characterized by excellent chemical resistance and high temperature resistance. These properties make PTFE seals particularly suitable for demanding applications. Whether as O-rings, flat gaskets, or custom molded parts, and whether in static or dynamic applications, PTFE can be flexibly adapted to specific requirements. Combinations with elastomeric materials are also possible, leveraging the advantages of both material families. Parker Prädifa offers a wide range of PTFE materials and expertise in the design of these seals.
