This Spears 401 series tee pipe fitting is made of schedule 40 PVC and has slip connections. This fitting is T-shaped and has three openings to connect and branch three pipes, two on the main run and one branch at a 90-degree angle from the middle of the tee. Pipe dimensions for tees are represented as A x B x C. "A" and "B" indicate the main run on the fitting, and "C" indicates the branch. It has female slip openings or "sockets" for sliding over the ends of male unthreaded pipes. The slip ends connect to pipes with a smooth bore for enhanced flow. This schedule 40 (standard wall) fitting is made of PVC for corrosion resistance, high strength, and less weight than fittings made from metal. It is compatible with schedule 40 PVC pipes and fittings and is suitable for cold-water pressure distribution systems including irrigation, pool and spa, potable water, and chilled water applications. PVC can be connected to other materials such as steel, copper, or cast iron using transition fittings. This tee pipe fitting provides superior flow to metal because of its smooth interior finish, which reduces friction and inhibits buildup of materials.

Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).
