A tee is a plumbing fitting that is commonly used in a wide range of applications. It is a T-shaped fitting that has three openings, with one on the top and two on the bottom. Tees can be made from a variety of materials, including copper, brass, PVC, and stainless steel.
One of the primary uses of a tee fitting is to connect three pipes together. This can be useful in a variety of plumbing applications, including water supply, drainage, and heating systems. The top opening of the tee is typically used for the main line, while the two bottom openings are used for the branch lines. By using a tee, it is possible to create a three-way intersection in a plumbing system, which can allow for greater flexibility and ease of installation.
