Jones Stephens b1440875 Black Iron Hex Bushing 4x1

Product Description

The JONES STEPHENS b1440875 is a black iron hex bushing designed to reduce a 4-inch female pipe thread to a 1-inch male pipe thread in iron or steel piping systems. This type of hex bushing provides a wrench-flat hex head for secure installation and removal using standard pipe wrenches or open-end wrenches. Manufactured from steel, it meets ANSI 372-2016 standards. It is a common fitting for connecting pipes or components of different thread sizes in gas, air, and fluid distribution systems. Plumbers, pipefitters, and mechanical contractors install this fitting in commercial and industrial applications where threaded black iron pipe assemblies are required.

This hex bushing is suited for use in black iron threaded piping systems found in commercial gas distribution, compressed air lines, and general industrial fluid piping. The hex shoulder design allows it to be installed directly into a female-threaded fitting or pipe end, bridging size transitions without the need for a coupling or nipple combination. It is appropriate for both new construction and retrofit work where pipe diameter reductions are needed at a single fitting point.

Key Features

• Reduces 4-inch female thread to 1-inch male thread in a single fitting
• Hex shoulder design allows wrench engagement for controlled tightening
• Steel construction meets ANSI 372-2016 standards
• Outside diameter of 4.70 inches with an overall length of 4.70 inches

Compatibility

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Shut off and depressurize the pipe system completely before disassembling or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten, as this can crack fittings or distort threads.
