Gather the Tools and Materials

Make sure you have the tools and materials needed before starting the pipe press process. In addition to the Ridgid RP350 you will also need copper 1 1/4″ pipes, press jaws that are compatible with the RP350 a calibrated pressing tool, pipe cutters, and a sanding tool. To ensure smooth operations, make sure your tools are well maintained.

Measure and Cut the Copper Pipe

Mark the length you want the copper pipe to be. Make a clean, precise cut with a pipe cutter. Remove any burrs, sharp edges or other irregularities with a deburring device to ensure proper fit and to prevent damage to press jaws.

The RP350 Press Jaws should be inspected and prepared.

The jaws should be inspected for any signs or damage. Verify that the jaws have been cleaned and are free from any debris that could interfere with the pressing process. Lubricate the jaws to reduce friction and improve pressing performance.

Position the Press Jaws

Install the press jaws on the Ridgid RP350 tool. Make sure they are aligned correctly and that the jaws are securely attached. Jaws should be snugly fitted around the copper pipe for a good press connection.

Press the Copper Pipe

The jaws should be positioned around the pipe join. You should apply steady pressure until you feel resistance and hear a click. Avoid using too much force because it can damage the pipe, or compromise the integrity of the connector.

Verify the connection

After pressing the pipe, you should inspect the joint for any leaks or irregularities. Visually check that the pipe has been pressed correctly and the joint secure. To confirm the integrity, you may conduct a test of pressure.

Repeat the Process

Repeat the above steps if you are making multiple connections. For consistent and reliable connection throughout your plumbing project, take the time to align and position the press jaws properly.
