The BMI 6644 is a 1/2 inch lead-free brass 90-degree elbow fitting with a chrome finish. It is used to change flow direction by 90 degrees in water supply piping systems. The lead-free construction meets federal and state requirements for potable water contact, making it suitable for drinking water applications. The chrome finish provides corrosion resistance and a clean appearance for exposed installations. Plumbers and pipefitters install this fitting in residential and light commercial plumbing systems where a right-angle direction change is needed in a supply line.
This elbow is suited for 1/2 inch water supply lines in residential and light commercial plumbing. Typical applications include under-sink supply connections, fixture drop-outs, and other potable water distribution runs where a 90-degree turn is required. The chrome finish makes it a practical choice for visible or semi-exposed installations where appearance matters alongside function.
Designed as an OEM-style replacement or new-installation fitting for 1/2 inch water supply piping systems in residential and light commercial plumbing.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before disassembling any existing connections. Use appropriate thread sealant or tape rated for potable water on threaded connections. Do not overtighten fittings, as brass threads can be damaged by excessive force.
