Brass all the way through. The 40X12 is a solid brass fitting, so it'll hold up well in most standard hydraulic and fluid line applications where brass is the right call. No surprises there.

Function-wise, it’s a male SAE 45 degree flare cap made for a 0.75 inch tube O.D. connection. It’s used to close off or protect a 45 degree flare end in a hydraulic or industrial setup.
