Step 1.

Cut the tube to length

  • Use a rotary tube cutter.
  • Ensure that the tube is cut square.
  • Check the tube has retained its shape and is damage free.
Step 2.

Deburr and remove all external sharp edges

  • Deburr the tube both internally and externally.
  • Where possible angle the tube downwards to prevent filings entering the tube.
  • Use a pencil type deburrer on internal tube edges.
  • Make sure the internal and external surfaces of the tube ends are smooth and free from burrs or sharp edges.

Step 3.

Clean the tube end

  • Thoroughly clean the tube end using ROTHENBERGER Rovlies or similar cleaning pad in a rotating action.
  • Tube ends must be free from scratches, oxidation, dirt and debris.
Step 4.

Check for defects

  • If deep scratches are still visible, cut the tube back to a clean section.
Step 5.

Ensure the O-ring is seated

  • Check the fitting is the correct size for the tube.
  • Check the O-rings are present and correctly seated.
  • A small additional amount of Conex Bänninger press fitting lubricant may be used to aid tube insertion.

Step 6.

Mark insertion depth on tube using depth gauge

  • Insert tube into correct socket in depth gauge.
  • Check window to see the tube is fully inserted.
  • Mark the insertion depth on the tube.
Step 7.

Alternatively insert tube to tube stop and mark

  • The tube must be fully inserted into the fitting until it reaches the tube stop.
  • To reduce the risk of dislodging the O-ring rotate the tube (if possible while slipping it into the fitting.
  • Mark the insertion depth on the tube.
Step 8.

Check the depth mark

  • Remove the tube and align with fitting socket, check that the depth mark is correctly positioned.
  • The insertion depth mark is used as a reference prior to pressing the joint.

Step 9.

Insert the tube fully into the fitting. Ensure tube is fully inserted prior to pressing

  • Insert the tube fully into the fitting up to the tube stop.
  • To reduce the risk of dislodging the O-ring rotate the tube (if possible)while slipping it into the fitting.
  • Prior to pressing ensure the tube has not moved out from the fitting socket.
  • Use the insertion depth mark as a guide.
Step 10.

Align jaws squarely on the fitting

  • Ensure pipework is correctly aligned prior to pressing.
  • Ensure the correct size jaw is inserted into the tool.
  • The jaws must be placed squarely on the fitting locating the groove on the bead.
  • The bead on the fitting should fit centrally in the groove of the jaw.
Step 11.

Complete the joint with the approved tool. Press once only

  • Depress and hold the button to complete the pressing cycle.
  • Pressing is complete when the jaws are fully closed and the piston retracts.
  • Complete the press cycle once only – do not repress.
  • Release the jaws from the pressing.

Step 12.

Mark the completed joint

  • Mark the completed joint after pressing.
  • This enable joints to be inspected easily before testing and insulating the pipework.
