Pressure & Temperature Ratings
All forged fittings are rated per ASME B16.11 pressure-temperature tables. Pressure class ratings (3000#, 6000#, 9000# for socket weld; 2000#, 3000#, 6000# for threaded) determine maximum working pressure at temperature. For specific pressure-temperature data, contact our team or refer to the product catalog.
