Thread Seals

Guarniflon® thread seals have been developed in the years in a special PTFE compound able to satisfy the following main requirements:
  • the perfect sealing application on the threads;
  • the necessary deformation (expansion) to overcome the thread and the following shrinking to the original dimension on the threads.
