How to Connect Copper Pipe to PEX Tubing

 

With the annual increase of PEX tubing utilization in domestic plumbing systems consumers are constantly retrofitting their piping systems. Most piping systems are originally constructed of Copper, CPVC, or PB piping. The need for retrofitting has grown rapidly in recent years due to older less efficient systems faltering. Most homeowners don’t see the need in re-piping whole systems due to minor expansions or a faulty pipe. When this is the case, the best possible variant is using an adapter to connect two different types of piping to co-exist within the same system. One such adapter connects Copper piping to PEX tubing, allowing the consumer to either add an existing line or replace a faltered one with ease.

 

Below are step-by-step instructions on how to properly connect PEX Tubing to Copper Pipe

There are two different methods to connecting copper pipe to PEX tubing : Crimp/Clamp Connections and Push-Fit/Speed-Fit Connections

 

Crimp/Clamp Connections

The more conventional connection method used with PEX tubing is the crimp/clamp method. This connection method utilizes a 360 degree compression of a crimp/clamp ring around the PEX tubing’s outside diameter to ensure a proper connection is made. The connection can then be checked with a Go-No-Go-Gauge to ensure a proper connection is made.
*Note* Solder Copper components first to ensure the PEX tubing is not damaged by the fire.

Step 1: You will need to solder the Copper end of the adapter together with the copper pipe using solder flux in the process.

Step 2: Once the Soldering Process is complete, slide the clamp/crimp ring of appropriate size onto the PEX tubing. Place the PEX tubing with the attached ring over the adapter.

Step 3: Use the necessary tool required to make your connection such as a Crimp or Clamp tool. Make sure that the ring is positioned over the middle of the adapter for a tight and secure connection.
