The ASC Engineered Solutions 8700129607 is a hexagon bushing in malleable black iron, designed to reduce a 1-1/2 inch male NPT connection to a 3/4 inch female NPT connection. This type of fitting is a standard threaded reducer used in gas, steam, oil, and general plumbing piping systems. The hex head allows a wrench to seat the fitting securely without slipping. At 0.45 pounds, it is a lightweight but durable component suited for both new construction and repair work. Licensed plumbers and pipefitters install this fitting where pipe diameter changes are needed in ferrous piping systems.
This bushing is appropriate for residential and commercial piping applications involving black iron pipe. Common install scenarios include gas supply lines, boiler piping, steam heating systems, and industrial process lines. The male thread measures 1-1/2 inches NPT and the female thread measures 3/4 inches NPT. It is sold individually and is well suited for maintenance, repair, and operations (MRO) situations where a concentric reducer is needed in a threaded iron system.
Designed as an OEM-style threaded hex bushing for use in standard NPT black iron pipe systems where a 1-1/2 inch to 3/4 inch reduction is required.
This fitting is installed by licensed plumbers or pipefitters working on threaded ferrous pipe systems. Shut off and depressurize the line before installation. Apply an appropriate pipe thread sealant or PTFE tape to the male threads before assembly. Follow applicable codes including IFGC and IPC requirements for thread engagement and joint preparation on gas and water lines.
