Standard copper tube
Suitable for domestic water, non-toxic and neutral water, and neutral alcohol solutions.
Nickel-copper tube
Known as nickel cupronickel, nickel-copper tube is suitable for use in seawater, river water, calcium chloride solution, ethylene glycol solution and other near-neutral pH solutions without sulfide contamination.
Aluminum brass tube
Often referred to as naval brass, aluminum brass tube may be used with river water, calcium chloride solutions, ethylene glycol solutions and in sea-water without sulphide contamination.
304/316L stainless steel tube
Suitable for corrosive environments that contain salts, inorganic acids, organic acids, alkalis, or other harmful substances. Cannot be used in solutions with chloride compounds.
Titanium tube
Titanium tube has unparalleled corrosion resistance in acidic, alkaline, and neutral saline solutions; it far surpasses the corrosion resistance of stainless steel as well as other non-ferrous metals.
