Lead Free Copper Union

Lead Free Copper Union

• Description：Lead Free Copper Union,including brass and copper parts with UPC,NSF61 approval.No lead free certified.
  The copper union's three parts all forged,then use CNC to process the thread.The two ends is made of pure copper and the middle parts is made of common brass.To make sure all the parts which touch the potable water are all made of copper.It is saft.
  The copper fittings known as copper pipe fittings,copper pressure fittings and copper plumbing fittings, divided to end feed copper fittings(wrot joint copper fittings ) and solder ring copper fittings(presolder copper fittings).And the quality of our EN1254-1 copper fittings can compare with yorkshire copper fittings(Pegler copper fittings) and connex copper fittings.our ASME B16.22 copper fittings also has exported to Mueller in U.S. the lead free copper union is no lead.The two end which touch to the water are all made of copper.It can replace some brass union if have no lead requirement.
