Asc Engineered Solutions 4354002400 Black Steel Nipple

Product Description

The ASC Engineered Solutions 4354002400 is a close-pattern black steel pipe nipple rated for extra heavy (XH) service. Manufactured from seamless black steel, this nipple measures 1-1/4 inches in diameter with a close-pattern length and a 1-1/2 inch overall dimension. It is designed for use in high-pressure or high-temperature piping systems where standard-weight fittings are not sufficient. Licensed plumbers and pipefitters install this type of nipple in commercial and industrial piping assemblies, including steam, gas, and hydraulic distribution lines where seamless construction and extra heavy wall thickness are required.

This nipple is suited for residential and commercial gas piping, steam distribution, and industrial process piping applications. Its seamless, extra heavy wall construction makes it appropriate for installations that demand greater structural integrity and pressure resistance than standard-weight threaded fittings provide. It is a common component in mechanical rooms, boiler rooms, and utility piping assemblies where black steel pipe and fittings are the standard of practice.

Key Features

• Seamless construction eliminates weld seams for greater pressure integrity
• Extra heavy (XH) wall thickness for demanding service conditions
• Black steel material compatible with gas, steam, and industrial fluid piping
• Close-pattern length minimizes space between fittings in tight installations
• Threaded ends for standard NPT connection to pipe fittings and valves

Compatibility

Designed as an OEM-style replacement or new-installation fitting for black steel threaded piping systems using 1-1/4 inch NPT connections in extra heavy wall configurations.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off all gas or fluid supply and depressurize the line before beginning any threaded connection work. Apply appropriate thread sealant or PTFE tape rated for the service medium. Do not overtighten threaded connections, as this may damage threads or distort fittings.
