C11000 Cu-ETP Copper Tube
C11000 has excellent corrosion resistance to weathering and very good resistance to many chemicals. It is often used specifically for corrosion resistance. It is suitable for use with most waters, and can be used underground because it resists soil corrosion. It resists non-oxidising mineral and organic acids, caustic solutions and saline solutions.
