PEX Expansion Connecitons
PEX expansion connections are a reliable and secure method for joining PEX-A tubing. Here's a guide on how to make a PEX expansion connection:
Cut the PEX tubing: Use a PEX cutter to ensure a clean and straight cut. Make sure the cut is perpendicular to the tubing.
Expand the PEX tubing: Slide a PEX expansion ring onto the end of the tubing. Position the ring so it's flush with the end of the tubing.
Expand the tubing and ring: Use a PEX expansion tool to expand both the tubing and the ring. Insert the expansion tool's head into the tubing and squeeze the handles to expand the tubing. Rotate the tool slightly between expansions to ensure even expansion.
Insert the PEX fitting: Once the tubing and ring are expanded, quickly insert the PEX fitting into the tubing. The tubing will contract around the fitting, creating a secure connection.
Check the connection: Ensure the connection is secure by visually inspecting and gently tugging on the fitting.
PEX expansion connections are specifically designed for PEX-A tubing, as this type of PEX has the highest degree of flexibility and memory, allowing it to return to its original shape after expansion.
