About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

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.

Copper-Nickel Unthreaded Pipe

For Use With: Air, Natural Gas, Oil, Water, Salt Water
Pressure Class : 200
Specifications Met: MIL-T-16420
Fittings: Use Class 200 copper-nickel

Designed for salt water applications, this pipe is made of copper-nickel, which has excellent resistance to stress cracking and better corrosion resistance than most stainless steel alloys. Pipe is also known as Pressure Class 200 pipe. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak. Pipe is seamless, which provides a smooth interior for unrestricted flow.
