The American Standard Threaded Four-Way Fitting is a pressure pipeline connection component compliant with the ASME B16.11 standard, utilizing the NPS (inch) diameter system to achieve four-way pipeline connections via threads. This fitting is available in three pressure ratings ranging from 2000 lb to 6000 lb, with sizes from 1/8“ to 4”. Wall thicknesses adhere to the SCH schedule system, and materials comply with ASTM standards. Widely used in pipeline diversion systems in industries such as petroleum and chemicals, its threaded interface design facilitates installation and maintenance, making it a critical diversion component in American Standard pipeline systems.
