The ASC ENGINEERED SOLUTIONS 766260483 is a 3-inch by 1-inch carbon steel threadolet rated for 3000 lb service. A threadolet is an integrally reinforced branch connection fitting that threads onto a run pipe and provides a threaded outlet for branch piping. This fitting is installed by pipefitters and plumbers on carbon steel piping systems where a branch takeoff is required without welding a full tee. The 3000 lb pressure rating makes it suitable for high-pressure process, industrial, and mechanical piping applications. At 0.77 pounds, this is a compact, single-piece fitting that simplifies branch connections on 3-inch header pipe down to a 1-inch threaded branch outlet.
This threadolet is used in industrial, commercial, and mechanical piping systems where a branch connection must be made on an existing run pipe. Typical applications include steam, compressed air, hydraulic, and process fluid piping. The 3-inch run by 1-inch branch configuration is common in header-and-drop piping layouts. This fitting is designed for use with carbon steel pipe and is compatible with threaded branch connections per standard pipe thread practice. Licensed pipefitters and mechanical contractors are the primary installers in both new construction and retrofit piping work.
Designed as an OEM-style replacement threadolet for 3-inch carbon steel run pipe with a 1-inch threaded branch outlet, rated for 3000 lb class piping systems.
Installation is typically performed by a licensed pipefitter or journeyman plumber. Depressurize and drain the piping system completely before cutting the run pipe or installing the fitting. The run pipe requires a correctly sized saddle cut to seat the threadolet properly before welding to the header. The branch outlet uses a standard tapered pipe thread connection; apply appropriate thread sealant and tighten to manufacturer and code-specified engagement per ASME B31.3 or the applicable piping code. Do not exceed the 3000 lb pressure rating of the fitting.
