Asc 8700129656 Hex Bushing Black Iron 1-1/2x1 In.

Product Description

The ASC Engineered Solutions 8700129656 is a malleable black iron hex bushing designed to reduce pipe size in threaded piping systems. It features a 1-1/2 inch male (NPT) thread on the larger end and a 1 inch female (NPT) thread on the smaller end, allowing a standard hex bushing installation with a wrench. Weighing 0.5 pounds, it is a dense, durable fitting suited for use in gas, water, and steam distribution lines. Plumbers and pipefitters install this fitting where a reducer bushing is preferred over a reducing coupling, particularly in tight spaces where a hex wrench hold is needed.

This bushing is used in residential and light commercial threaded pipe assemblies. Common applications include water supply lines, low-pressure gas distribution piping, and compressed air systems. The malleable iron construction allows it to withstand mechanical stress and mild vibration better than cast iron. It is suitable for above-grade and indoor installations where black iron fittings are code-appropriate.

Key Features

• Malleable black iron construction for improved ductility versus standard cast iron
• 1-1/2 inch male NPT thread x 1 inch female NPT thread configuration
• Hex body allows secure wrench grip during installation and removal
• Meets Federal Specification WW-P-471-B for ferrous plugs, bushings, and locknuts
• Dimensions conform to ANSI B16.14; pipe threads conform to ANSI B2.1

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded piping systems using 1-1/2 inch to 1 inch black iron pipe reducers.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC or IFGC requirements. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate pipe thread sealant or PTFE tape to the male threads before assembly. Do not overtighten; use the hex body with a pipe wrench to achieve a proper seal without stressing the fitting.
