Vitoflon O-rings are designed to close off potential leaks between mating surfaces in both static and dynamic applications. FEP and PFA encapsulated Viton O-rings combine the excellent chemical resistance of PTFE with the elastic behavior of an elastomer to impart memory to the seal.

Vitoflon O-ring

Viton combines exceptional mechanical properties with compression set resistance so it can recover rapidly from deformation. It offers a very good chemical and temperature resistance (up to 250 °C). FEP is used for all applications up to 205 °C and is resistant to virtually all chemicals and joined by an advanced heat moulding process to give a seamless encapsulation. PFA has the same properties as FEP but with greater heat resistance for applications above 205 °C.

Key properties

  • Resistant to agressive chemicals
  • Gas permeability
  • Adaptive sealing force of an elastomeric O-ring
  • Resistant to compression set/cold flow issues of solid O-rings

Applications

  • Pomp
  • Mobile Hydraulic
  • Standard/hydraulic cylinder
  • Pneumatics
  • Presses injection moulding machines
  • Excavator
  • Machine tools
