This is a heavy-duty wall-mounted supply elbow, often called a 'wall elbow' or 'drop ear elbow.' It's used when you're installing a hand shower or a showerhead on a slide bar – it's the fitting that gets mounted inside the wall and provides the connection point for the shower arm. This one is made from solid brass with a matte black finish, so it's built to last and won't corrode.
It has a built-in check valve, which is a really useful feature that helps prevent hot water from accidentally backing up into your cold water line (which can cause 'shower shock' or temperature fluctuations). The threads are standard 1/2-inch NPT (National Pipe Taper) on both the inlet (female) and outlet (male). It even comes with a pure copper converter and ceramic flow restrictor to make installation easier and help save water. If you're doing a bathroom remodel or installing a new shower system, using a quality fitting like this ensures a leak-free, reliable connection for years. The compact 90-degree design saves space and looks clean.
