Cut the tube to length

We recommend you use a Rothenberger tube cutter. It is important to ensure that the tube is cut completely square. Tube ends should be clean and free from scratches not less than the socket length. Check the tube has retained its shape.

NOTE: The tube cutter shall not have been used for cutting carbon steel/ferrous metals. Failure to ensure this may result in a corrosion failure point.

Remove the burns

Make sure that the internal and external tube end is free from burrs or sharp edges by using a deburring tool to prevent damage to the O-ring. Then wipe the tube end clean to avoid damaging the O-ring on tube insertion.

Check the fitting

Inspect the fitting, checking the O-ring(s) are present and correctly seated and that the fitting is the correct size for the tube.

Mark the insertion depth

The tube must be fully inserted into the fitting until it reaches the tube stop in order to make a perfect joint. Marking insertion depth will ensure that any tube movement is detected, which is especially important if the joints are to be pressed at a later time.

NOTE: Do not measure the socket depth but push the tube into the fitting then mark the tube.

Assemble the tube and fitting

To assemble the joint, the tube must be inserted into the fitting up to the tube stop. (Use the mark on the tube which was made earlier as reference). The pressing operation should only be undertaken when the tube reaches the tube stop.

Complete the joint with the press tool

Ensure that the correct size jaw for the fitting is inserted into the tool. The jaws must be placed square on the fitting. Depress the trigger/button to begin the compression cycle of the tool. This is complete when the mouth of the fitting is fully enclosed by the jaws. Now release the jaws from around the fitting. (For further information refer to complete Romax instructions.)

NOTE: The >B< Press Stainless Steel joint is complete after one complete compression cycle of the tool. Do not crimp any >B< Press Stainless Steel fitting more than once.
