Asc Engineered Solutions 1DXE.BB Hex Head Pipe Bushing

Product Description

The ASC Engineered Solutions 1DXE.BB is a hex head pipe bushing designed to reduce a 1-1/2 inch male NPT (MNPT) thread down to a 3/4 inch female NPT (FNPT) thread. Cast from black cast iron and pressure-rated at 125 lb, this bushing is a standard reducing fitting used in low-pressure piping systems for gas, water, and steam applications. The hex head profile allows for wrench engagement during installation. Plumbers and pipefitters install this fitting when transitioning between pipe sizes in threaded iron pipe systems.

This bushing is suited for residential and light commercial piping installations where threaded black iron pipe is the standard material. Common applications include natural gas distribution lines, steam heating systems, and low-pressure water supply piping. It is domestically manufactured, making it a compliant choice on projects with domestic content requirements.
