Macomb Group Approved 1DXE.BFB Black Malleable Iron Flush Bushing

Product Description

The MACOMB GROUP APPROVED 1DXE.BFB is a standard black malleable iron flush bushing used to reduce pipe thread sizes within a fitting connection. This type of bushing threads directly into a female-threaded fitting, allowing a smaller male-threaded pipe or fitting to connect without an additional coupling. It fits a 1.5 inch female thread and reduces to a 0.75 inch male thread. Black malleable iron construction makes it suitable for gas, air, and general industrial piping systems. Plumbers and pipefitters install this fitting during rough-in and final connection work on low-pressure piping assemblies.

This flush bushing is used in residential and light commercial applications where a compact, low-profile thread reduction is needed inside an existing fitting socket. Common install scenarios include gas distribution piping, compressed air lines, and black iron pipe systems where space is limited and a hex bushing would add unwanted length. The flush style sits flush with the face of the receiving fitting, keeping the assembly tight and clean.

Key Features

• Flush design reduces thread size without adding significant length to the fitting assembly
• 1.5 inch female NPT inlet to 0.75 inch male NPT outlet
• Black malleable iron construction for use in gas, air, and general-purpose piping
• Standard NPT threading for compatibility with standard pipe and fittings
• Compact profile suits tight spaces where a hex bushing would not fit

Compatibility

Designed as an OEM-style replacement or stock fitting for standard NPT black iron pipe systems in residential and commercial plumbing and gas piping applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable code requirements including IFGC and IPC where gas or water service is involved. Shut off gas supply or depressurize the line completely before disassembling any threaded connections. Apply approved thread sealant or pipe tape to all NPT threads before assembly and tighten to hand-tight plus the appropriate number of turns per standard practice. Do not over-tighten malleable iron fittings, as the material can crack under excessive torque.
