The John Guest SuperSeal union is specifically designed to provide extra grip on stainless steel tubing. Each fitting in this series features a collet with integrally molded stainless steel teeth and a hand-operated nut and wedge-shaped plastic washer that applies extra pressure to the collet and the double O-ring seals. This allows the collet teeth to bite thoroughly into the tube to provide grip, while at the same time, compressing the O-rings to further improve the seal.

  • Used to connect stainless steel tubing
  • Acetal body with double Nitrile O-Rings
  • The nut and wedge-shaped plastic washer apply extra pressure to the collet and the double O-ring seals
  • Connect, disconnect, and reconnect in seconds without tools
  • Food Quality and suitable for potable liquids and pure water applications
  • Made with lead free materials

Working pressure and temperature:
