TruFlow manifolds have R20(a name for the size of the thread) outlets to connect to loops run in a hydronic heating system.  Wirsbo makes "Fitting Assemblies" to connect from the R20 thread to PEX Tubing.  There are three types of fitting assemblies sold at SupplyHouse.com.  QS-Style fitting assemblies which are compression style and require no special tool, Propex fitting assemblies which require a Propex Expander tool, and Multicor compression style fitting assemblies which are made for use with Multicor PEX-AL-PEX Tubing.
