    Cut the Pipe To Length

    Use a pipe cutter to cut the pipe flat across the pipe to the marked length. Use a deburring tool to eliminate any burrs or sharp edges from the freshly cut end of the pipe. Clean the exterior of the pipe with a cleaning brush or emery cloth to remove any contaminants, grease, or oxidation.

    Assemble The Connection

    Slide the pipe into the fitting until it reaches the stop. Make sure the fitting is correctly aligned with the pipe. Use a marker to draw a line on the pipe at the edge of the fitting. This will help you ensure the fitting is crimped in the right place during pressing.

    Secure The Connection

    Position the press tool jaws around the fitting, ensuring they're aligned correctly. Activate the press tool to crimp the fitting onto the pipe. The press tool will exert the necessary force to create a secure and leak-proof connection. Release the press tool jaws and remove the tool from the fitting.

  6. Verify The System

    After installing all the fittings, test the system. Pressurise the system and inspect for any signs of leakage at the connections. If you detect any leaks, re-press the connection or replace the fitting as required.


Copper press fittings offer a fast and reliable method for joining copper pipes. By following these steps and using the appropriate tools, you can achieve a secure and leak-proof connection for your plumbing system.
