The Parker tee is a brass t-shaped pipe fitting with male National Pipe Taper (NPT) threads on all three ends for connecting and branching female pipes. It has NPT threads for creating tighter seals than straight threads and is made from brass, which is more economical and offers greater corrosion resistance than steel. This fitting meets standards ANSI B31.1 and B1.20.1 for quality assurance. 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). Parker Hannifin is a global manufacturer of motion and control technologies.
