The complete offering, which is manufactured from high-quality, C36000 brass, includes 31 transition fittings that convert ProPEX connections to male thread, female thread, copper tubing sweat, copper fitting sweat and copper fitting press. Note that because these are C36000 brass fittings, they are not for potable applications.
