The ProPEX Auto Rotation Adapter is a great, lightweight tool that can improve the quality of your installation while making your job so much easier. The adapter automatically rotates the expander head on each expansion to avoid creating grooves on the PEX tubing. This allows you to get in even tighter spots since you don't have to turn it manually. The tool fits on all ProPEX Expander Tools (except for the ProPEX 200 Battery Expander Tool) and is compatible with all standard expander heads.
Be sure to get the ProPEX auto rotation adapter if you use the expander system for your PEX installation, it will be well worth it for the time and effort it saves you!
