  • Low tightening torque and clamping force rises with the internal pressure.
  • Safe joint every time
  • Leak free O-ring seal
  • Demountable and reusable, can be used with most tube materials.
  • Low installed cost, no welding (so inert gas purging, NDT and excessive flushing are not required), minimal tube preparation and no special assembly equipment required.

 

  • Nut - mild steel, stainless steel or cupro-nickel. Compatible with most environments. Closes split collet and retains sealing mechanism.
  • Back-up washer - mid steel, stainless steel, or cupro-nickel. Provides additional support for the tube and locates the o-ring.
  • Body - mild steel, stainless steel or cupro-nickel. Compatible with most fluids and environments. Located o-ring and tube.
  • O-ring - nitrile, FPM (Viton), EP or FEP encapsulated FPM. Compatible with most fluids. Highly resistant to leakage even under severe vibration, pressure pulsation and temperature cycling. Provides diametric seal between tube OD and Body cavity.
  • Derate by 50% for high pressure gas systems
  • Pressure ratings based on the tube OD tolerance to BS360? and DIN2391C
  • 3:1 safety factor
  • Split collet - mild steel, stainless steel or cupro-nickel. Clamping force rises with pressure. Large clamping area ensures minimal deformation of the tube. Retains tube in position.
