Monel Ferrule Fittings

Monel Ferrule Fittings for leak-tight instrument and hydraulic lines, available on MetalMitra in imperial and metric sizes to ASTM B366 / ASME SB 366, with mill-certified traceability on every lot.

Monel 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.

Monel alloys are nickel-copper alloys known for high strength and excellent resistance to seawater, hydrofluoric acid, alkalis and many reducing environments.
