Brass fittings are small components made from an alloy of copper and zinc, commonly used in plumbing and piping systems. They connect different sections of pipes, allowing for the flow of liquids or gases. Their durability and resistance to corrosion make them ideal for both indoor and outdoor applications. These fittings come in various shapes and sizes, including elbows, tees, and couplings. They are often used in water supply lines, heating systems, and gas lines. The versatility and strength of brass fittings make them a popular choice in both residential and commercial installations.
