The tee 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 National Pipe Taper (NPT) threads for connecting to male threaded pipes, creating a tighter seal than straight threads. This fitting is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability, and it is forged to increase the material's strength and resistance to mechanical shock and vibration. The fitting has an operating temperature range of -65 to +250 degrees F.

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).
