The Tefen compression tube fitting is made of fiberglass polypropylene and connects to tubing on all ends. This is a tee with three openings and is used for connecting and branching three pipes. This fitting is made of fiberglass reinforced polypropylene for indoor, outdoor, and field applications, and is resistant to chemicals and fertilizers. The operating temperatures range from 39.2 to 194 degrees F. The working pressure for this fitting is up to 200 pounds per square inch (psi). It uses metric unit measurements for industry consistency.

Pipe and tube fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. 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 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).
