Brass compression nut fittings are components used in plumbing and piping systems to connect tubes or pipes together securely without the need for soldering or welding. They are commonly made of brass due to its durability, corrosion resistance, and malleability.
These fittings typically consist of three main parts: a compression nut, a compression ring (also known as a ferrule), and the fitting body. The compression nut is threaded onto the fitting body, and the compression ring is placed over the tube or pipe before insertion into the fitting body. As the nut is tightened onto the body, it compresses the ring against the tube, creating a tight seal.
These fittings are widely used in applications such as water supply lines, gas lines, air compression systems, and hydraulic systems. They offer a reliable and leak-proof connection that can be disassembled and reassembled multiple times without compromising performance. Additionally, they are relatively easy to install and require minimal tools compared to other types of fittings.
