Asc 4354001290 Black Steel Xh Nipple 1/2 in X 5-1/2 in

Product Description

The ASC ENGINEERED SOLUTIONS 4354001290 is a black steel seamless extra heavy (XH) pipe nipple sized at 1/2 inch by 5-1/2 inches. It is manufactured from black steel to ASTM A106 Grade B specifications, giving it the wall thickness and pressure rating required for demanding piping installations. Pipe nipples like this one are threaded fittings used to connect two female-threaded pipe segments or fittings within a run of pipe. The extra heavy wall classification makes it suitable for higher-pressure service where standard-weight fittings would not meet system requirements. Licensed plumbers and pipefitters are the primary installers of this type of fitting.

This nipple is suited for use in industrial, commercial, and mechanical systems where black steel pipe is specified, including steam lines, compressed air distribution, gas distribution headers, fire protection systems, and hydronic heating systems. The 1/2 inch nominal pipe size and 5-1/2 inch overall length fit common close-quarter runs between valves, tees, and unions. It is imported and not domestically manufactured, which should be noted for projects with domestic-content requirements.

Key Features

• Extra heavy (XH) wall construction for elevated-pressure piping service
• Seamless black steel body to ASTM A106 Grade B material standard
• 1/2 inch nominal pipe size with 5-1/2 inch end-to-end length
• Both ends threaded NPT for standard pipe system assembly
• Non-domestic origin — suitable for general commercial and industrial use

Compatibility

Designed as an OEM-style replacement or new-install fitting for 1/2 inch NPT black steel pipe systems requiring extra heavy wall nipples.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical codes such as the IPC or IFGC. Apply an appropriate thread sealant or pipe thread compound rated for the intended service medium before assembly. Shut off and depressurize the piping system completely before removing or installing any threaded fitting. Do not over-tighten threaded connections, as this can crack fittings or distort threads.
