Which end of the fitting goes to the pex pipe


Hi, One way to identify the Polybutylene Brass Transition Coupling is by the rings around the coupling. The side of the coupling with less rings connects to the PEX. The black crimp ring goes with the PEX side. The side of the coupling with more rings connects to the Polybutylene along with the copper colored crimp ring. If you have any more questions you can call tech support at 877-700-4242. (Kind regards,)
