What is the primary function of pipe fittings?

The primary function of pipe fittings is to connect sections of piping and change direction. This essential role allows for the efficient routing and assembly of piping systems, which is crucial in various applications such as heating, cooling, water supply, and waste management. Without fittings, it would be challenging to create a continuous and functional piping system, as they facilitate not only the joining of different pipe segments but also enable the redirection of flow when needed.

While supporting the weight of the piping system, providing insulation, and allowing access for maintenance are important aspects of overall pipe installation and system design, they do not encapsulate the fundamental purpose of fittings. The primary task of these components lies in their ability to connect and direct flow, making them indispensable in the successful installation and functionality of a piping system.
