U.S. TAG to ISO/TC 131/SC 4 - Connectors and similar products & components

Committee Mission

The U.S. TAG to ISO/TC 131/SC 4 develops USA industry’s input on International (ISO) standards for connectors (sometimes called fittings and couplings) and conductors (tubes and hoses). Examples of topics covered are port and stud end systems, testing of connectors, flange connectors, threaded connectors and nominal dimensions of tubes and hoses.
