Copper Nickel Ferrule Fittings

Copper Nickel Ferrule Fittings for leak-tight instrument and hydraulic lines, available on MetalMitra in imperial and metric sizes to ASTM F1387, with mill-certified traceability on every lot.

Copper Nickel Ferrule Fittings are compression-type tube fittings that use front and back ferrules to grip the tube and create a reliable, leak-tight seal without welding.

Copper nickel (Cu-Ni) alloys such as 90/10 and 70/30 offer excellent resistance to seawater corrosion and biofouling, combined with good thermal conductivity and fabricability.
