Pipe fitting and other valves can control the flow of water, gas, and even sewage. They regulate pressure and help save energy by preventing excess pumping. There’s a gate valve, globe valve, check valve, ball valve – all these different options! A pipe fitting is a type of valve that connects two different pipes. The fittings come in various shapes and sizes, with the most common ones being threaded or welded. Pipe fittings are often used to connect pipes when extending piping systems, replacing worn connections, repairing leaks, or diverting flows away from one section of the system to another.
