Cam and Groove Couplings top of page

  • Extremely easy to open and close without inserting clips or pins. Ideal for vibration tolerant locking.
  • Resistant to accidental disconnection when dragged.
  • Cast-in lugs allow safety clips to be attached once the lugs are passed through slots in the special cam lever arms. These clips prevent the coupler from being unlocked until they are removed, providing a positive locking action
  • Durable stainless steel cam arm pins will not rust or bind.
  • Recess holds gasket firmly in place, ensuring proper placement.
  • Long shank design allows proper banding thus eliminating the major cause of hose damage.
