Sealing elements and support rings made of PTFE and PTFE compounds

Sealing Gaskets

Using the materials mentioned, HEUTE+COMP. manufactures sealing elements and O-ring supports according to your specifications. PTFE support rings prevent high pressures from extruding O-rings into sealing gaps and damaging the rings as a result.      

Due to its cold flow characteristics and high degree of abrasion, pure PTFE is only conditionally suitable for sealing. Accordingly, a wide range of PTFE compounds have been developed to account for all involved parameters.

  • Temperature
  • Media influence
  • Pressures
  • Sealing gaps
  • Assembly conditions

Additionally for dynamic applications:

  • Material and surface of the sliding counterpart
  • Speed

The technique used to process a material also influences its properties. For instance, a material filled with glass can be made gas-tight through special heat treatment. For this reason, our team offers consultancy early on during the development phase in order to select appropriate materials for your application.
