  • Ensure the copper tube is cut squarely
  • Deburr the pipe internally and externally to form a smooth edge
  • Check that the ‘O’ ring of the fitting is seated correctly and free from impurities
  • Do not use jointing compound, oil or grease
  • Insert the tube to the full depth of the socket
  • Clearly mark the tube at full depth
  • Aline the fitting with the jaw of the tool correctly
  • Make the press connection, using a suitable M profile jaw.
