Brass Fitting refers to various types of plumbing and piping components made from brass, a corrosion-resistant alloy of copper and zinc. These fittings are widely used in residential, commercial, and industrial plumbing systems to join, connect, or adapt different pipes and fixtures. Brass fittings come in different shapes, sizes, and configurations, including couplings, tees, elbows, adapters, valves, and connectors.
