To properly expand Pex-A tubing using the Wirsbo Expander Tool, you must fully separate the handles and insert the head into the tubing. Then bring the handles together at least 5 times for 3/8" tubing, 4 times for 1/2" tubing, 8 times for 3/4" tubing and 14 times for 1" tubing before inserting the ProPEX Fitting.
