The SMC KP series union tee fitting is made of polypropylene and has tube connectors. This union tee fitting is T-shaped and has three female openings to connect and branch three pipes, two on the main run and one branch at an 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 is a push-to-connect fitting that accepts the insertion of nylon, soft nylon and polyurethane tube fittings. The fitting is made of polypropylene, which resists most chemicals, has excellent dimensional stability, and can be sterilized. The working pressure for this fitting is up to 522 pounds per square inch (psi), and its operating temperature ranges from -20 to 80 degrees C.

Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. Push-to-connect compression fittings do not require tools or sealants, and are useful in installations where a heat source, such as a soldering torch, is prohibited. 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).
