Encapsulated O-Rings

All standard "CHEM-RINGS" are produced in two dedicated units, in modern, advanced factories. These two facilities have been highly developed in recent years. 
  • FEP/PFA Encapsulated 'O' Rings 
  • Silicone or Viton core
  • Hole Core
  • Square section
  • 43 standard cross sections
  • Internal diameter - standard or you choose
  • Over 1.5 million Encapsulated 'O' Rings stocked
  • FEP/PFA Encapsulation Complies with part 177 of title 21 of the FDA
FEP Teflon® tubing has:
  • A wide of chemical resistance.
  • High corrosion resistance.
  • Low compression set.
  • Low coefficient of friction.
  • Temperature range of -60°C to 205°C (-76°F to 400°F).
  • FDA, USP CLASS VI, SANITARY 3A compliant.
PFA Teflon® tubing has:
  • All the benefits of FEP tubing.
  • A higher temperature range of -60°C to +260°C. (-76°F to 500°F)
  • A higher mechanical strength.
  • An increased stress and crack resistance.
  • Longer wearability.
