Design
  • PTFE encapsulated Viton O-rings have a core of homogenous Viton Material with a moulded PTFE sheath on the outside.
  • PTFE encapsulated orings are designed to protect the core O-ring material from attack by aggressive chemicals as well as increase the effective temperature handling range.
Material
  • PTFE encapsulated 70A Duro Silicone - Precision Moulded.
Application
  • PTFE, whilst being highly inert and able to withstand aggressive chemicals and high temperatures, also has a very high compression set and no effective memory and is therefore a poor option to replace a traditional elastomeric O-Ring. In coating a Silicon Core with a thin layer of PTFE, the respective benefits of both materials is harnessed.
Fluids
  • Hydraulic fluids, petroleum fuels and oils
  • Resistant to solvents and harsh chemicals.
