The ASC ENGINEERED SOLUTIONS 766260525 is a 4-inch by 1-1/4-inch threadolet fitting designed for branch outlet connections in high-pressure piping systems. Manufactured from carbon steel with a 3000 lb pressure rating, this fitting allows a threaded branch takeoff directly from a run pipe without the need for additional fittings or welded couplings. It is installed by licensed pipefitters and plumbers working on industrial, commercial, and mechanical systems where reliable, pressure-rated branch connections are required. The threaded outlet simplifies field assembly and ensures a secure, leak-resistant connection.
This threadolet is suited for use in carbon steel piping systems in industrial plants, commercial mechanical rooms, and process piping applications. The 4-inch run pipe size paired with the 1-1/4-inch branch outlet makes it appropriate for reducing branch configurations in steam, water, gas, or oil distribution lines that operate within the fitting's rated pressure limits. It is commonly specified on projects requiring ASME or ANSI-compliant branch outlet fittings.
Designed as an OEM-style replacement or new-installation threadolet fitting for 4-inch carbon steel run pipe with a 1-1/4-inch threaded branch outlet in 3000 lb-rated piping systems.
Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical and piping codes. Depressurize and isolate the piping system completely before fitting installation or removal. The saddle contour must be properly matched and welded to the run pipe before the threaded branch connection is made. Use appropriate thread sealant rated for the service medium and pressure class.
