Brass fittings are a type of plumbing fixture that is made out of brass, a type of metal. Brass fittings are used to connect two pieces of plumbing together. There are many different types of brass fittings, including brass couplings, elbows, brass tees, and caps. Brass fittings are often used in water systems because brass is a corrosion-resistant metal. This means that it does not rust or corrode over time, which can cause leaks in plumbing systems. Brass fittings are also relatively easy to solder, which makes them a popular choice for connecting metal pipes together. An on/off valve is a brass fitting that is used to turn the water flow on and off. This fitting is often found near the water meter. Brass compression fittings are one of the most widely used types of brass fittings. They are incredibly easy to install, and they can be used with a variety of different materials, including copper, PVC, and CPVC. Compression brass fittings consist of two elements: a compression nut and a compression ring. The compression nut is threaded onto the end of the pipe, and the compression ring is placed over the end of the pipe and screwed down tight. This creates a seal that prevents water from leaking out. Brass is durable and long-lasting. It won’t corrode or rust like some other materials, making it a reliable choice for plumbing applications. Brass is also resistant to bacteria and other contaminants, making it a safer option for potable water systems.
