Auto rotation adapter With the Propex Auto Rotation Adapter, installers no longer need to rotate the expander tool or the tubing itself by hand when making Propex connections on Wirsbo AAQUAPEX tubing and Wirsbo HEPEX plus tubing. Adapter automatically turns the expander head on each expansion of the tubing. Good for tight spaces where manually turning tubing or tool is difficult. By automatically rotating the expander head on the tool, the lightweight adapter simplies installation for more consistent PEX connections and avoiding a slow seal, especially in cooler temperatures.
