Metric Pipe & Tube Fittings by ISO Specification

ISO Specification Metric In general, the difference between tubes and pipes is in how they are specified. Tubes are generally specified by their outside diameter, and pipes are usually specified by their inside diameter. Fittings are the connectors (Elbows, Crosses, Tees, etc.), that are used to join segments together or to interface with them.
