EX and Aquatherm fans rejoice: Aquatherm’s newest PEX adapter is zero-lead and can be used for potable water. It includes zero-lead brass and is manufactured to ASTM F1960. A new male-end design allows you to fuse directly into fusion outlets, so they are quicker and easier to install. Unlike the other PEX adapter (F1807) Aquatherm offers which has a PP-R socket, this adapter has a street connection that is welded directly into an Aquatherm fitting. Aquatherm can be used as the main distribution pipe and transition to PEX as needed. Dimension available: 1/2″. More sizes to come.
