What is a C70600 Pipe Nipple?
A pipe nipple is a short length of pipe with male threads on both ends (or one end), used to connect two other fittings or pipe sections.
C70600 (CuNi 90/10) is a copper-nickel alloy containing 90% copper and 10% nickel, with excellent resistance to seawater corrosion, stress cracking, and biofouling. It is the material of choice for piping components in saltwater, naval, and offshore environments.
