Asc Engineered Solutions 1DX1B.BB Hex Head Pipe Bushing

Product Description

The ASC ENGINEERED SOLUTIONS 1DX1B.BB is a hex head pipe bushing used to reduce a larger threaded pipe opening to a smaller one within a piping system. It features a 1-1/2 inch male NPT outer thread and a 1-1/4 inch female NPT inner thread, allowing inline size reduction without the need for a coupling and nipple combination. Rated at 150 lb, this bushing is constructed from malleable iron with a black finish. Plumbers, pipefitters, and mechanical contractors install this fitting in gas, water, and steam distribution systems where a compact threaded reducer is required.

This bushing is suited for residential and light commercial piping applications including gas supply lines, compressed air distribution, and hydronic heating systems. The hex profile on the outer body allows a wrench to be applied for secure installation without damaging the fitting. Its domestic manufacturing origin makes it appropriate for projects with domestic-content procurement requirements.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable code requirements including the IFGC and IPC. Shut off and depressurize the piping system fully before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten malleable iron fittings, as the material can crack under excessive force.
