Fast, efficient and consistent, this tool makes installing small bore Pex fittings a breeze - see video. The turning of the expansion heads reliably expands all of the pipe evenly which, in turn, enables even contraction thereby avoiding leakage.

The expansion heads constantly move so it is important to apply a thin layer of the special grease (supplied) to the cone and castellations on the tool. It's also very important to ensure the expansion heads are seated properly, centered and engaged with the castellations.

The first connection I fitted had ten expansions of the half inch pipe and the fitting was not fully tight after about twenty seconds. The second connection had seven expansions, as did the third and they were both fully tight after about twenty seconds. The fourth connection I fitted had just six expansions and the fitting was fully tight after only five seconds. There are probably a lot of factors that affect the rate of expansion and, therefore, compression and with more use I can see this tool being even faster than Milwaukee claim.
