Copper-Nickel Butt-Weld Pipe Fittings
Fittings weld flush against pipe, creating a strong connection that permits maximum flow. Fittings are also known as Pressure Class 200 fittings. They are copper-nickel, which has excellent resistance to stress cracking and better corrosion resistance than most stainless steel alloys. They are often used in highly-corrosive environments, such as salt water applications.
