Asc 4354002450 Black Steel Xh Nipple 1-1/4 X 4 Inch

Product Description

The ASC ENGINEERED SOLUTIONS 4354002450 is a black steel seamless extra heavy pipe nipple sized at 1-1/4 inches by 4 inches. Extra heavy wall construction provides greater pressure-bearing capacity and resistance to mechanical stress compared to standard weight fittings. The black steel material suits gas distribution, steam, and industrial piping systems where uncoated steel is specified. Licensed plumbers, pipefitters, and mechanical contractors install this type of nipple when connecting threaded pipe runs that require a short, rigid close-to-close extension between fittings, valves, or equipment takeoffs.

This nipple is suited for commercial and industrial piping applications including natural gas supply lines, compressed air systems, steam distribution, and hydraulic process piping. Its seamless construction eliminates the weld seam, making it appropriate where consistent wall thickness and higher pressure ratings are required. The 1-1/4 inch nominal size fits a broad range of valve, union, and fitting connections common in mechanical rooms and utility systems.

Key Features

• Seamless extra heavy wall construction for higher pressure ratings than standard weight nipples
• Black steel material compatible with gas, steam, air, and industrial fluid systems
• 1-1/4 inch nominal diameter by 4 inch overall length
• Threaded ends for connection to standard NPT fittings, valves, and flanges
• Import-sourced fitting meeting A106B material specification for seamless carbon steel

Compatibility

Designed as an OEM-style replacement or new-install component for threaded black steel piping systems using 1-1/4 inch NPT connections in commercial and industrial mechanical applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Fuel Gas Code or ASME B31 piping standards. Shut off and depressurize the system fully before removing or installing any threaded nipple. Apply appropriate thread sealant or PTFE tape rated for the service fluid before making up connections. Do not over-torque threaded joints; use a backup wrench on adjacent fittings to prevent stress on connected components.
