This Spears schedule 40 PVC tee fitting has socket openings on each end and female NPT threads on the branch, and is suitable for connecting three pipes. The socket ends connect to pipes with a smooth bore for enhanced flow, and the National Pipe Taper (NPT) threads create a tighter seal than straight threads. The 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. aAa¥ and aBa¥ indicate the main run on the fitting, and aCa¥ indicates the branch. The fitting is made of white PVC (polyvinyl chloride) for chemical and 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. The fitting has a maximum operating temperature of 140 degrees F, meets ASTM International D1784 and D2466 standards for quality assurance, and is certified by National Sanitation Foundation International (NSF) for potable water service. This schedule 40 PVC tee fitting is suitable for connecting pipes for conveying drinking water, waste water, chemicals, and other liquids in a range of industries.\n\nPipe 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).\n\nSpears Manufacturing produces thermoplastic fittings and valves for fluid, drain, waste, and vent systems.
