Penn Machine 3980601101 Hex Head Pipe Bushing 2x1-1/4 in

Product Description

The PENN MACHINE 3980601101 is a forged carbon steel hex head pipe bushing designed to reduce a 2-inch male NPT connection down to a 1-1/4-inch female NPT connection in high-pressure piping systems. With a dual pressure class rating of 3000 and 6000 lb, this bushing is built for demanding industrial and commercial applications where fitting integrity under pressure is critical. Manufactured by Pennsylvania Machine Works and meeting multiple ASTM standards, it is installed by licensed plumbers, pipefitters, and mechanical contractors working on process, utility, and high-pressure steam or fluid lines.

This bushing is suited for industrial process piping, commercial mechanical systems, and heavy-duty plumbing installations where a threaded reduction from 2-inch to 1-1/4-inch is required. The hex head design allows for standard wrench engagement during installation and removal, making it practical in tight or congested pipe chases and mechanical rooms. Its forged construction and carbon steel material make it a reliable choice for high-pressure gas, steam, water, and oil service lines where cast fittings are not appropriate.

Key Features

• Forged carbon steel construction for superior strength over cast alternatives
• Dual pressure class rating of 3000 and 6000 lb for versatile high-pressure service
• MNPT x FNPT end style provides a 2-inch male to 1-1/4-inch female threaded reduction
• Hex head design allows secure wrench engagement during installation
• Meets ASTM A105, ASTM 181 Grade 1/2, and ASTM 234 Grade WPB/WPC standards

Compatibility

Designed as a standard threaded pipe bushing for use in 3000 lb and 6000 lb class carbon steel piping systems requiring a 2-inch MNPT to 1-1/4-inch FNPT reduction.

Installation Notes

Installation is typically performed by licensed pipefitters or plumbers in accordance with applicable mechanical and plumbing codes such as the IPC or ASME B31 piping standards. Always depressurize and isolate the piping system completely before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape rated for the service media before threading the bushing into the female fitting. Do not overtighten; use a pipe wrench on the hex head and follow fitting engagement guidelines for NPT threads.
