PE-X Pipes & Fittings Joining Instructions

Cutting

Cut the pipe vertically by pex pipe cutter. Make sure to cut it quickly and precisely.

Selecting PEX Fitting And Jaw

Choose the right size of PEX fitting and jaw of the crimping tool.

Sleeving

Put the copper crimp ring over the PEX pipe at the open end. Later, insert the PEX fitting body into the pex pipe until the shoulder of the fitting reach the pipe, make sure the insert is completely inside the pipe, and the contact between fitting and PEX pipe is clean and free of impurity.

Pressing

Open the crimping tool and put the PEX fitting into the jaw. Press the jaw until it closes completely. While pressing, make sure the crimping jaw is vertical to the pipe, the pressing contact must be free of impurity.

Checking

Use the GO/NO GO gauge to check whether the pressing is completed. If the crimp ring slides into the "GO" slot, but stops at the shoulder in the "GO" slot, then the pressing is acceptable.
