Brass Pipe Fitting, 2 Inch 90 deg Street Elbow

Brass through and through, no plating or coating involved. The 2 inch refers to the nominal pipe size, which is standard NPT sizing used across most pipe fittings in that range. A street elbow like this one has a male end on one side and a female end on the other, so it threads directly into a fitting or port without needing a separate nipple in between. That setup saves a connection point when you're working in tight spots.
